X X 1. It supports the NS16550 UART chips in full FIFO mode. X 2. It supports modem sharing for input and output. X Microport almost supported this feature but none X of the other vendors did. X 3. It supports hardware flow control. X X X This driver should work with most of the UNIX SYS V/386 3.X ports X currently available. You can have both this and the original X vendor driver in the same kernel. Each driver controls its own X separate set of serial ports. The only restriction here is that X any int vector must not be used by more than one of the drivers. X The kernel config program will complain otherwise. X X Note: This driver supports neither VP/ix nor DosMerge virtual X serial devices. If you need COM ports for your DOS programs X you have to connect the needed devices to ports that are X controlled by the original vendor async driver. You won't X have the special features of the FAS driver on these ports, X though. If you don't need to access serial ports from DOS X the vendor driver can be removed from the kernel. X X------------------------------------------------------------------------ X XA little about what it does: X X This driver supports shared line usage by having two logical X devices sharing one physical line. To those familiar with X Microport this is very similar. For the other readers a X brief description follows. For each line there are two X names. For example for the first line the names are ttyF00 X (minor device 0) and ttyFM00 (minor device 192). The ttyF00 X is used for cu, kermit, and other programs that want to dial X out. It ignores the modem signals and just goes to it. The X ttyFM00 line is strictly for getty. When getty calls open on X ttyFM00 the driver hangs the open until the modem asserts the X carrier detect signal and then lets the open complete. If cu X opens ttyF00 while getty is waiting for the open to complete X the device is given to cu and the getty open must wait for cu X to finish and then will again wait for the carrier. If cu X tries to open the ttyF00 line while getty has ttyFM00 open cu X will get an error. If getty tries to open ttyFM00 while cu has X ttyF00 open the getty open will just hang and wait for cu to X close the line and then wait for the carrier. To put it simply X you should put up a getty on ttyFM00 with a -t 60 and use ttyF00 X for cu and uucico. X X The modem devices ttyFMxx is the minor device of ttyFxx plus X 192. There are several other possible minor devices for X each port. See the description in `fas.c'. X X------------------------------------------------------------------------ X XA little about what it supports: X X The driver supports and has been tested on many async cards X and mux boards. It supports most combinations of shared X interrupts. The current driver supports NS16450, NS16550 and X um82450. It is also reported to work on the 8250B. I X suspect that it will not work on some of the earlier 8250 and X 8250A parts, due to various bugs and speed problems in these X early parts. Since these parts have no place in an 386 or other X high performance systems I did nothing to try to support them. X X Take a look at the various samples of space-xxxx for details X of how to set up for various devices. X X X A WORD ABOUT CHARACTER LOSSES X ----------------------------- X X If you experienced character losses with your vendor async X driver at high baud rates you shouldn't blame the vendor for X that. The real reason for this problem lies in the ancient port X devices used in most 386 systems: The 8250 and the NS16450. X X They have only one receiver character buffer. This implies that X the operating system must read a character from this buffer before X the next one arrives from the port's shift register. For the old X IBM PC with DOS this was sufficient. But for UNIX and with baud X rates up to 38400 this is simply a joke. X X UNIX is not a real-time operating system. That means that it's X kernel isn't optimized for fast interrupt responses. With the X proper hardware this is no problem. But because the vendors have X to adapt UNIX to the standard hardware found in 386 systems they X also have to cope with the NS16450 ports which are in there simply X to be compatible with IBM PCs, XTs and ATs. X X It is impossible to make it work at high baud rates without a X major redesign of the AT&T supplied UNIX kernel. But then it X wouldn't be UNIX SYSV any more. X X Luckily, there is a pin-to-pin replacement available from X National Semiconductors: The NS16550A. X X This device has separate 16 character FIFOs for the receiver and X the transmitter. With these FIFOs the interrupt latency of the X kernel can be quiet high without losing any characters. X Additionally, because with most interrupts many characters are X processed at once the system is loaded much less. X X As you see, the necessary hardware is available. Therefor, if you X have to blame the UNIX vendor then blame him for not telling you X that you should buy some NS16550A and/or for not supplying you X with a serial driver that supports these port devices. X X But as you have the FAS driver now and if you use the NS16550A X devices you shouldn't have this kind of trouble any more. This is X the philosophy behind the driver's name `Final Async Solution'. X X Enjoy!

X X------------------------------------------------------------------------ X X XRelease History: X X release 1.1a Sat Nov 11, 1989 X X This is an unofficial release as I'm not the original author X of this async driver. X X Uwe Doering gemini@geminix.mbx.sub.org X Billstedter Pfad 17 B X 1000 Berlin 20 X West Germany X X New Features: X X Added a third minor tty device number for every physical X port. See description preceding the asyopen function in X asy.c. Changed the behavior of ttyxx, too. X X Added output hardware handshake support for DSR. Now you X can do handshake with CTS, DSR or both. Input hardware X handshake is on if you use at least one of the output X handshake signals. X X More flexible support of additional interrupt registers X on mux boards. This is fully configurable now. X X Added support for the CREAD flag. If not set, receiver X interrupts are still serviced, but the received characters X are simply thrown away. This is not as elegant as disabeling X the interrupts themselves, but with the already existing X driver it was the easiest way, and the most new-bugs-preventing, X too. X X Added a lot of comments to the source so that the curious X user can understand why and how things are done. X X X Bug Fixes: X X The hang-up-on-last-close flag (HUPCL) was ignored. DTR X was asserted regardless of this flag. X X Made the detection of CTS and DCD more bullet-proof. X Especially because between a close and the next open of X a line, where interrupts are ignored, the software copys of X CTS and DCD must be set up propperly in the asyopen function X or the tty line would be blocked under certain circum- X stances. For similar reasons, there is also a setup in the X asyparam function. X X Rewrote the input character processing function to work X according to the TERMIO(7) man page. X X Changed the behavior of BREAK generation to let the X transmitter drain before TX is set to low. X X Changed line hangup procedure so that the closing X process returns immediately and doesn't sleep during X the hangup delay/time. Instead, if an other process tries X to open the line while hangup is still in progress, this X process will sleep until hangup is competed. X X With DOS Merge, on MicroPort V/386 3.0e the linker was X missing the function `init8250'. Reengineered this from X a disassembler listing of MicroPort's original driver and X modified it to work with the NS16550 16-bit FIFO. This X funktion was added simply to be able to link the kernel. X DOS Merge's virtual COM ports are still unusable with this X release, though. To include this function, add a `-DMERGE' X to the CFLAGS line in your makefile. X X Made a lot of other corrections and enhancements in both X speed and functionallity. As a result of all my effords X I think this driver is slightly faster, more versatile X and much more stable than the original release. X X ------------------------------------------------------------ X X release 1.1b Sat Nov 25, 1989 X X New Features: X X Changed the minor device number scheme again. X There are now two main groups: The unblocked open X and the blocked open. Every group has four sub-modes X and an additional hardware handshake flag. All this X is coded in the higher four bits of the minor device X number. Because of this, the maximum of 32 ports was X reduced to 16 ports so that the port number fits into X the remaining lower four bits of the minor device number. X 32 dumb ports in a single machine would have been overkill X anyway. For more details refer to the comment above the X `asyopen' function in the file `asy.c'. X X ------------------------------------------------------------ X X release 2.00 Mon Nov 27, 1989 X X As this release differs so much from the original version I got, X I now declare this as independant from the original author X Jim Murray. This allows me to introduce new release levels X without wondering whether they will collide with Jim's releases. X Of course many credits to Jim for writing this software in the X first place. Without his driver as a base I never would have X been able to do such kernel driver development. X X Bug Fixes: X X If there were glitches on the hardware handshake lines X and the DCD line a getty on this port would sometimes X hang and become an immortal process. I think this was X because the output buffer wasn't flushed properly X on carrier loss. I hope I fixed this now. We'll see. X X ------------------------------------------------------------ X X release 2.01 Tue Nov 28, 1989 X X Did some cleanup in the source code. X X I splitted the driver into two parts: The driver itself and X the file `space.c'. X `space.c' contains all data structures necessary to configure X the driver and is compiled at kernel link time. Therefore if you X change your serial card configuration you simply change `space.c' X directly in the link kit directory and relink the kernel. No X driver recompilation or installation is necessary for this. X But note that whenever you use `make install' your setup in X the link kit directory is overwritten by the original `space.c' X file. Therefore you should copy your new `space.c' back to X the source directory when you are finished with the configuration. X X Renamed the package to `FAS Final Async Solution'. The following X files have been renamed: X asy.c -> fas.c X asy.h -> fas.h X asy_conf-xxxxx -> space-xxxxx X X ISC 386/ix is supported now. There are separate makefiles X for uPort and ISC to cope with the differences in link kit X installation. X X Bug Fixes: X X `getty' still hung sometimes on a line with hardware X handshake. Tried to fix it this time. X X ------------------------------------------------------------ X X release 2.02 Thu Nov 30, 1989 X X Abandoned the distinction between space-xxxxx files with X and without hardware flow control because this is selected X by the minor device number now. X X Bug Fixes: X X Set the high and low water marks for hardware input flow X control to higher values than software flow control. This X gives precedence to software flow control if both methods X are used. These marks are self-adjusting and don't need to X be changed if some flavor of UNIX has a different buffer X size than the standard 256 characters. Before this change X concurrent use of both flow controls could cause trouble X with some high-speed modems. This is fixed now. X X A flush read or write buffer request now also clears the X receiver or transmitter FIFO, respectively. An ioctl X call with a TCSETA* command clears the FIFOs, too. X X ------------------------------------------------------------ X X release 2.03 Fri Dec 01, 1989 X X Wrote an installation guide. The driver should be quite X easy to install now. X X Added tty node configuration files for ISC. X X Hardware input flow control is bound now to the level of the X receiver ring buffer instead of the UNIX input buffer. This X has the advantage that buffer size and trigger levels are X defined in the driver and therefore can be varied as needed. X X New Features: X X Added a boot time status message that shows the init X state of each port. This tells you immediately what X ports are found and initted by the driver. Useful to X determine hardware configuration problems. Refer to X file fas.c (function `asyinit') for a description. X Thanks to Kritt Gierlewsen for this proposal. X X ------------------------------------------------------------ X X release 2.04 Thu Dec 07, 1989 X X Did some cleanup in the source. X X Removed the FIFO clear from the ioctl function. We don't want X to do things there that aren't in the book. X X An ioctl call that switches off the CLOCAL flag will create X a SIGHUP signal if the carrier is actually missing at this X time. X X Every device is tested now quite thoroughly during initialization. X If the test fails the corresponding device keeps unconfigured. X X ------------------------------------------------------------ X X release 2.05 Sat Jan 13, 1990 X X This is the first public release of the FAS driver. X X Special thanks to the sysops of my test sites, Axel Fischer and X Kritt Gierlewsen. X X FAS is now an independant driver with its own driver name (`fas'), X major device number, link kit directory and other things necessary X for a driver. The original asy driver may or may not be linked X with the kernel. You only need it if you want to access some X serial devices via the virtual COM ports of the DOS emulator X (DosMerge or VP/ix) because the FAS driver doesn't have this X (really vendor dependant) feature. X X The default prefix for tty device node names is `ttyF' now. X This prevents mix-ups with the device names of the original X asy driver. X X Dropped the SYSV/AT support. I couldn't test the driver X for several release generations on uPort SYSV/AT, and because X there are not very much systems left with that flavor of UNIX X it doesn't make sense to try to maintain compatibility with it. X If someone really wants to use this driver on a 286 he has X to port it himself. X X Improved the transmitter FIFO fill procedure. Now it will try X harder to fill the FIFO as much as possible to cut down on X transmitter interrupts. X X Software input flow control (XON/XOFF) is controlled by the driver now. X It is bound to the level of the receiver ring buffer (as is hardware X flow control). As usual, it can be switched on and off by the X IXOFF flag in the termio structure. X X Changed and speeded up the ring buffer -> unix buffer processing. X X For ISC, the getty lines for the inittab file are installed X by the makefile now. X X The conditional compilation of the function `init8250' (for X DosMerge) is now controlled by a define in `fas.h'. The compiler X switch `-DMERGE' is not used any more. X X Improved the documentation. X X The signals used for modem control and hardware flow control are X fully configurable in the space.c file now. Look at fas.h for X possible macros and combinations. X X There are some new modes for hardware flow control, for instance X HO_CTS_ON_DSR. This means that CTS is only looked at if DSR is on. X If DSR is off output is possible regardless of CTS. The underlying X assumption here is that we can expect proper handshake handling X only from devices that are in the ready state (indicated by DSR). X As a spin-off the problem with the hanging getty on lines with X turned-off terminals (mentioned in earlier releases) should be X gone if you use this new mode. X X If the XCLUDE-Flag is availabe (SYSV 3.2 because of Xenix X compatibility) exclusive open of a device is possible. X X The default size of the input ring buffer is now 5000 bytes. X This makes streaming input more likely even on loaded systems. X X Bug Fixes: X X The task state busy flag wasn't reset in some rare cases. X This could cause processes to become immortal while waiting X for the busy flag. X X Under some special conditions an ioctl call with a TCSETA? X command could corrupt the last character in the transmitter X shift register. This is fixed now. X X More fixing of the busy flag handling was necessary. X Co-ordinating several delayed tasks controlling this flag X is kind of tricky. X X After a TCSETA* ioctl command we disable the transmitter X for 2 sec (measured from the last transmitted character) X if the character format and/or speed has changed. This X gives the receiving side some time to do the same changes. X This is kind of experimental. There may be applications that X suffer from this delay. You may change the #define ADAPT_TIME X in fas.h to a smaller value. X X ------------------------------------------------------------ X X release 2.06 Fri Mar 16, 1990 X X This should have been patch #3 for release 2.05, but there are X so many changes now that I decided to make it a new release. X Therefor some of the changes are described in the 2.05 release X notes above but were never released to the public. X X New Features: X X There is a transmitter ring buffer now to make the output X less system load dependent. This really speeds things up X because the transmitter FIFO gets filled with more characters X at once. The buffer size depends on the actual baud rate to X prevent long output buffer drains at low speeds. X X There are also bigger input buffers to make FAS more competitive X against "intelligent" cards. X X Lots of speed improvements and many small changes. X X Bug Fixes: X X Fixed input/output buffer flush on carrier loss while close X is waiting for the output to drain.
