I have what I hope is a simple question. What I would like to know is the title or author of a book that gives the information needed to help write a communications program that can access files with different protocols. I belong to a local BBS and certain files use a protocol that my Hayes Micromodem does not know and causes it to go into a death pause. The host (a thing called an IBM) is waiting for something, but my Smartcom has no setting for it, so they just sit there and hum at each other. The host supports X-MODEM and a couple others, but I do not know the format of the routines necessary. I am not looking for code, mainly some reference material that my public library and bookstore do not seem to carry, or I have just overlooked. While there are excelent programs, both free and at a cost that do what is needed, I find it more interesting writing my own than ending up as a User of others' code? I have written an assembler version to access a full-screen terminal, but that was for a 300 baud internal on my APPLE II+. What I want to write is for a Hayes 1200 that interfaces through a Super Serial Card so that I can access either full-screen or line-by-line. Thank you for any help you can offer.

Network Comment: to #1637 by powe.henr801E@XEROX.COM I'm interested in the same thing you are (i.e. writing my own terminal program). It appears that you are far ahead of me. If you can give me any suggestions on how to do SSC i/o, specifically how to use the Pascal 1.1 entry points to write a term program and how to keep the modem active while accessing the keyboard and drive, I would be forever appreciative. Thanks...Terry Johnson

I have what I hope is a simple question/request. What I would like to know is the title or author of a book/article/whatever that gives the information needed to help write a communications program that can access files with different protocols. I am not looking for free code. I know there are excelent programs, both free and at a price, that do what is needed, but I find it more interesting writing my own than ending up as a User of others' code. I have written an assembler program to access a full-screen terminal, but that was for a 300 baud internal (a Hayes Micromedem)on my APPLE II+. What I want to write is for a Hayes 1200 that interfaces through a Super Serial Card (the major stumbling block) so that I can access either full-screen or line-by-line. Thank you for any help you can offer.

C Programmer's Guid to Serial Communications by Joe Campbel, Howard W. Sams & Company, full retail is 24.95. This book mainly gets into Xmodem communications, and of course all the code is in C. It also just covers two UARTs, the 8250 and Z80SIO. (sounds like an ibm eh?). It also has some good information on error detection, information transfer etc. The information transfer gets into Kermit somewhat, Xmodem, etc. It does give some good information on most things involved in communications, but is slanted towards ibm. But then again, communications is not slanted towards any machine, since the background information is on ARQ, send-wait ARQ, Continuous ARQ. Its coverage of basic communications is done quite well thought. Of course it does not mention the SSC. scott hutinger mser001@ecncdc.bitnet

I have tried several times to get a reply to the following, but have never gotten anything back. I would be interested in any answer that meant this got somewhere. What I would like to know is the title or author of a book/article/whatever that gives information, like formats, that would be helpful in writing a communications program that can access files with different protocols. I am not looking for free code. I know there are excelent programs, both free and at a price, that do what is needed, but I find it more interesting writing my own than ending up as a User of others' code. I have written an assembler program to access a full-screen terminal, but that was for a 300 baud internal Hayes Micromedem on my APPLE II+. What I want to write is for a Hayes 1200 that interfaces through a Super Serial Card (the major stumbling block) so that I can access either full-screen or line-by-line under program control. Thank you for any help you can offer.

Okay, I'm not sure how much help this will be, but I'll give it to you anyway. I saw something on AppleLink, in one of the forums, in a folder about books, relating somewhat to this. Somebody had posted a small review of a book about modem programming, giving lots of info, I take it. It wasn't an apple specific book, and I believe that although it had code samples, they were in C, which may not be of all THAT much use to you, but at least it's a start. Hope it is of at least some help. Jonah
