Van_Camp (LCWSL) <kvancamp@ARDC> To: info-ibmpc@usc-isib Subject: Undigestification I've been receiving the info-ibmpc digest for a while now, and I think it's time I found out how to read this a little more efficiently. A posting like the recent one summarizing the entire Xmodem protocol can be a real hassle, because of the excessive length. I'm on a Unix system, and our modified mail utility works great for most messages. Since I get the digest as one huge mailing, however, there is no way of reading it except: (1) paging through it with More; or (2) going through the editor [slow on our mainframe]; or (3) downloading to my PC where I can use some quicker file scan utilities like BROWSE. None of these three solutions is particularly convenient, especially compared to my normal mail utility. Since I imagine there are a lot of people in similar situations, I figured someone out there has probably come up with an elegant solution. What I'm looking for is a C program or shell script for Unix that will separate out the messages in the digest and present some simple options like paging only through selected messages based on the subject or sender name. Of course I could write such a program myself, and I probably will if no one else responds. [Several options exist here. One such program is on <INFO-IBMPC>UNDIGESTIFY.C - and is currently untested. Secondly, there is an "undigestify" macro for gnumacs/rmail. And for TOPS-20 users, the BABYL library has an undigestify function. Each is designed to break a digest into its component messages. --Elmo] At the very least, I would be satisfied with a version of More that lets me page backwards as well as forwards in a file. Something like BROWSE on the PC. Speaking of BROWSE, by the way, does anybody have any documentation on this? This is an excellent file scan utility, and I know it's public domain but I can't remember where I got it from. I use it all the time to page through files, but I know there's more to it because when I press certain keys I get curious error messages that suggest there are other commands available. I've checked through the usc-isib and Simtel20 archives, but I can't find it. Any help on how to use more of its features, or a pointer to the documentation, would be appreciated.

Van_Camp (LCWSL) <kvancamp@ARDC.ARPA> cc: info-ibmpc@USC-ISIB.ARPA All the editors agree the digests are too long. Also our turn around for publishing messages is too long. More shorter digests are a nice ideal but appear to be impractical for this all volunteer effort. Frequently I include things like the XMODEM protocol document purely for archival purposes. Once I put something in a digest I can usually find again. Usually I try to put such messages at the end of a digest, but often forget to do this. I will make this a new year's resolution. I think it is wonderful if sites do stuff to make reading and archival of digests easier. We would be glad to keep such software in our program library. Unix specific stuff is probably best distributed via normal unix communications media as we don't speak unix here and wouldn't know what to do with it. I have always prefered terminals with scrolling memory. At ISI we always had Hewlett Packard terminals so I use Dick Gillmann's VDTE which emulates a HP terminal with 7 pages of scrolling memory per terminal line (the program allows two simultaneous connections if you have two com ports.) Kermit also has scrolling memory (although I believe less). I find scrolling memory real useful for reading long things like digests. I can scan just fine at 9600 baud and usually find I am just getting interested in something as it is rolling off the top of the screen. I then hit the ^S and page back to read the article. Try Kermit as your terminal emulator it might make reading digests easier. Now is a good time for everybody to send in their complaints and suggestions for the future of INFO-IBMPC. The editors (who rarely see each other) will be meeting some time this month. We probably will be looking for more volunteer help once we get organized. ------------------------------ Date: Fri, 3 Jan 1986 18:36 MST Sender: KPETERSEN@SIMTEL20.ARPA From: Keith Petersen <W8SDZ@SIMTEL20.ARPA> Subject: Source for ARC450 now available The source code for ARC450, the latest ARChive program for MS/PCDOS is now available from SIMTEL20 as: Filename Type Bytes CRC Directory PD:<CPM.PCDOS> ARC450SR.LBR.1 BINARY 71680 8CBAH --Keith ------------------------------ Date: Fri, 3 Jan 1986 18:38 MST Sender: KPETERSEN@SIMTEL20.ARPA From: Keith Petersen <W8SDZ@SIMTEL20.ARPA> Subject: QMODEM version 1.33 now available In response to bug reports, the author of QMODEM has released QMDM113, which is now available from SIMTEL20 as: Filename Type Bytes CRC Directory PD:<CPM.PCDOS> QMDM113.ARC.1 BINARY 152320 AB2DH --Keith ------------------------------ Date: Thu, 2 Jan 86 09:47 EST From: "Roger C. King" <RCKing@MIT-MULTICS.ARPA> Subject: XON/XOFF support for COM1 (LaserWriter) I just received a pointer to a new routine (30Sep85) on SIMTEL20, XONXOFF.ASM in pd:<cpm.pcdos> which, after assembly, works for me using XyWrite III and the Apple LaserWriter. It must be made into a .COM file, and only run once at boot since it doesn't check to see if it is already resident and keeps using more memory if you try and run it each time you go into a program which will use it. It was put into the public domain by Frank Whaley of MicroPro International. The COM file requires only 171 bytes! Thank you Frank Whaley.

To refer to an actual device, use (for example) "\dev\con."

Call 800-538-3373 and say you are a developer. AST and Quadram provide the same service for their superset of the spec. Look for an ad from one either one of them for the appropriate phone number -- I don't have it handy. aa ------------------------------ Date: Wed, 1 Jan 86 14:31:33 pst From: <ubc-vision!watale!comptrol1@uw-beaver.arpa> Subject: Sources of Expanded Memory Spec's Official copies of the Lotus/Intel/Microsoft Expanded Memory Specification are available by writing or calling: Intel Corporation 5200 N.E. Elam Young Parkway Hillsboro, Oregon 097123 Mailstop TOC-03 1-800-538-3373 (or 1-503-629-7367 from outside the U.S.A.) and ask for Technical Support. As far as I know the current release is 3.20. The proponents of this memory specification request users to register themselves with Lotus so that updates to the specification may be automatically distributed. The specification details the software interface only. Intel has not released the hardware specifications as of this date (to the best of my knowledge). The alternative is the AST/Ashton-Tate/Quadram Enhanced EMS specification. Current revision level is 3.0 for software, 1.0 for hardware. Copies of the specification can be obtained by writing or calling: AST Research Inc. 2121 Alton Avenue Irvine, California 92714 1-714-863-1333 ext. 5906 AST is distributing future releases of the specification as it is revised. Both hardware and software specifications are provided. For those interested in a review of expansion cards supporting either of these specifications see: Enlarging the Dimensions of Memory Charles Petzold, Phil Wiswell, and Winn L.

You can use output redirection to capture the output of basic programs much like "Photo" captures screen output on Tops-20 systems. If the console displays are set up to include blank lines between "prints" to the screen the contents of the "photo" file are pretty legible. This is useful if you have a program that is used for iterative calculations and you want to have a record of the session. To do this just invoke the redirection when you enter basic. Ex. A>basica ttest > ttest.out This records the screen displays from the program ttest in the file ttest.out. I believe a Control-C will close the output file. Perhaps, exitting from basic will also do this, but I am not sure since I mostly use this with a program that I generally just Control-C out of. Dave Zubrow@c.cs.cmu.edu ------------------------------ Date: Fri, 3 Jan 86 13:35 EST From: Elefante@RADC-MULTICS.ARPA Subject: Fastback Algorithm To: info-ibmpc@USC-ISIB.ARPA >Fastback allegedly copies files much faster than DOS copy. >Does anyone know how they do it? It's my understanding that Fastback uses the Direct Memory Access feature of the IBM/PC to allow the disk controller to write data to the disk at the same time the cpu is preparing the next chunk of data for export. The overall result is blazing fast disk writes. I use Fastback and love it. Since I only have one floppy in my system, I really can't keep up with the capabilities of Fastback as well as I could if I had two, since Fastback immediately writes to the next floppy available. It seems that no sooner have I slipped a disk into the slot for writing that it is crying out for the next. That's really not quite true, since it takes about 20 seconds or so to fill a formatted disk (formatting is automatic and also blazing fast), but after using the DOS Backup bulldozer, this seems like driving a Porche. My only complaint is that Fastback comes copy protected, and you need to submit another $25 to get the uncopyprotected version. I have no problem with that except that I haven't received the copyable version yet and it's been well over a month. I understand they are fixing some bugs before releasing it. On the other side of the coin, I received my original by Federal Express two days after ordering it by phone. I paid $119 under an introductory offer, but have since seen it advertised for $99. It's worth the price just watching it, and the restore user interface is magnificent. -- Don Elefante ------------------------------ Date: Thu, 2 Jan 86 09:26:42 PST From: walton%Deimos@CIT-Hamlet.ARPA Subject: Fastback algorithm To: blue@nbs-sdc.arpa I believe that the Fastback file transfer algorithm is as follows: two DMA channels are used simultaneously, one to read data from the hard disk into a floppy-sized internal buffer, the other to write this data from the internal buffer to the floppy. The program formats a track on the floppy on one rotation of the disk, then writes the data onto that track on the next rotation using the second DMA channel. The data are written in some strange format, probably compressed--DEBUG won't touch Fastback floppies. Hope this helps.

I have an AUTOEXEC.BAT file which includes it on a menu. It _D_O_E_S_ work with DOS 3.1 (At least the AT version) and MS-DOS will not accept any more keystrokes after you put the disk to sleep. It sort of acts like the key is locked. But isn't that what you want? I have the dreaded CMI 20 Meg disk, which is one reason I am so picky about using shipdisk. We have used shipdisk on some other 20 Meg Type 2's but nothing else.

I've read a lot of adds on both and don't really have a good feel for what's available. I've got a feeling that quite a few of the systems are for ATs only.

Can this card be set to start at 128 KB boundaries? Can someone supply a table/formula for setting the switches? (I have the AT Tech. Ref., but there isn't anything on this expansion board in it. I also have the Adv. Diag., but the tables in it are just a repeat of those in the Inst. and Setup -- 512 KB boundaries only.) ------- -------
