OK, now that I have rs232 working on Minix-ST what can I do with it? Anyone have sources for XMODEM, YMODEM , or anyother MODEM ? How about Kermit sources? UUCP anyone? Howard Johnson ATT-BL lzaz!hcj

Howard,
How about the KA9Q TCP/IP package? there are MIDI and AUX drivers.
How fast is supported? The package has Telnet, SMTP and FTP as well
as finger on the newer versions...

I have the sources (as, I imagine, would many others) to X/YMODEM, SEAlink, and one or two others that elude me at the moment. I also have a few uucp sources here, one sould compile for V7, has Andy seen any? I was surprised to find that one wan't included when I first read his book. If anyone is really interested I may be able to organise an anonymous ft or a posting. 4 hours until 1989, if '88 was the year of networking and Unix, what will '89 be like, AARRRRRRRGGGGGGGGGGGGGHHHHHHHHHHHHHHH! I think I'll just get drunk...... Byeeeee, Paul.

The reason I didn't mention X/YMODEM in the book probably has to do with the fact that I don't have the foggiest idea of what (it is)/(they are). I know about uucp, kermit, X.25, 802, and OSI. Does this supersede any of these? I hope it supersedes OSI, because that is the one most in need of being superseded. For MINIX, I suspect kermit is going to be the standard file transfer mechanism (other than the Amoeba networking for people with Ethernets). Kermit is available on all known machines, and the MINIX version seems pretty stable and reasonably efficient. Andy Tanenbaum (ast@cs.vu.nl)

Here is the source (hopefully compatible with V7, can't check yet) for an
XMODEM protocol driver. Can someone please send me feedback as to whether
or not it works? I think it should run faster than KERMIT, but it requires
8,N,1 line settings, good luck.
I hope that the code illustrates the idea of XMODEM to you Andy. Any further
info reqd?
yours,

/*
* XMODEM -- Implements the Christensen XMODEM protocol,
* for packetized file up/downloading.
*
* I have tried to keep the 4.2isms (select system call, 4.2BSD/v7 tty
* structures, gettimeofday system call, etc.) in the source file
* getput.c; but I make no guarantees. Also, I have made no attempt to
* keep variable names under 7 characters (although a cursory check
* shows that all variables are unique within 7 first characters).
* See the README file for some notes on SYS V adaptations.
* The program has been successfully run on VAXes (4.3BSD) and SUN-3s
* (2.x/3.x) against MEX-PC and ZCOMM/DSZ.
*
* -- Based on UMODEM 3.5 by Lauren Weinstein, Richard Conn, and others.
