I would like to know if there is any documentation out there on how to write a serial driver for UNIX System V on a 386? Has any body out written a serial driver like this? Please respond at kozlevca@picker.com

There's a chapter in John Valley's "UNIX Programmers Reference",
MacMillan/Howard Sams Publishing.

There's always the standard "Writing System V/3.2 Device Drivers" that should be available from your O/S vendor, and the AT&T "Block and Character Interface: Programmers Reference & Guide". (I have them at home if anyone want's the PEC or Select-Code numbers.) I also have two books specifically about kernel innards and writing device drivers (also at home), and notes from a tutorial about writing drivers. -- Greg A.

Another book I know of is "Implementing Device Drivers", published by NCR Inc. Well written, but off course some examples point to NCR's Unix implementation (on Tower's, but not to specific versions). It incorporates all sorts of drivers: TTY, Vitual Disks, general RS232, I/O boards, general character devices (tapes and everything) and describes all sorts of considerations to make in respect to bus-vectors, various hardware specifics, memory and how to finally implement things in the kernel. Thru the years it helped me a lot. The ordernumber of the thing I have in front of me right now is D1-0713-A, but there might be a successory release at the moment. Dick.

Pick up a copy of FAS (Final Async Solution) at any fine FTP site near you, and read the code. Unlike the samples given in many books (eg: SCO Device Driver Guide), this one actually works, _and_ has all the bells and whistles. In fact, you probably won't need to write your own -- FAS supports 16550 UARTS, AST (and clone) 4-port cards, and has flow control that actually works. ---=---=---=---=---=---=---=---=---=---=---=---=---=---=---=---=---=--- Paul Nash Free Range Computer Systems cc paul@frcs.UUCP ...!uunet!m2xenix!frcs!paul
