I am looking for the source for programs that can be used to do upoloads and downloads of software between an IBM-compatible type pc and a host system. The system i use here at work is a VAX 11/780 running Berkley-Unix 4.1. Also if i can not get the source any information regarding methods for uploading/downloading between a pc and a host-system (VAX) would be appreciated. I am specifically interested in methods that do error detection without a great detrement to the speed of the file transfer process. -- Barry Kimelman [ UUCP address: ...!philabs!micomvax!barry ] phone: (514) 341-5680 ext. 336 (7:30 AM to 5:00 PM eastern time) Nothing is impossible if you do not have to do it yourself !!

Suggestions, in order of my own preference: A) For the PC: 1) YAM (Yet Another Modem), by Chuck Forsberg. Advanced professional communications tool, capable of advanced control scripts, polling, batched, lengthy, speedy unattended transfers, and terminal emulation of the adm3a and the vt52. About $110 from various sources, like The Programmers Shop. Contact me if you need more info. 2) PC-TALK II. This is a "freeware" program written in BASIC (blech), but intended to be compiled. It's quite outstanding given the limitations of the programming language the author chose. Available for downloading from Compuserve, or contact me for the author's address. You send him $35 if you like the program. 3) Crosstalk. An off-the-shelf, overpriced but highly functional communications tool. Compared to YAM, this is overrated, but it's very easily available through almost any PC shop. B) For the VAX (or almost anything else) under Unix, almost any version: 1) UMODEM. Public domain. I'll uucp it or post it if there's enough demand, to net.sources. Works well under 4.xBSD if compiled with the -DVER7 switch, and works well under Sys III/V if compiled with the -DSYS3 switch. Also has similar conditional definitions for USG and other Un*x variants. (Lauren Weinstein and others contributed to this program.) 2) SB/RB (send batch/receive batch). For YAM batched transfer compatibility. Also public-domain, written by YAM's author. I'll similarily make it available to anyone who asks, or, if demand is sufficient, I'll post it to net.sources. 3) UC. By Richard Conn @SIMTEL20.ARPA (and others?). Same deal with posting or uucp'ing. Also p-d. XMODEM is a superior file transfer protocol in the public domain and originally written by Ward Christensen. It is more robust than KERMIT, but I'm a little biased; we also have quite a bit of KERMIT stuff available that we've received from site okstate; I don't use it but others here do and they like it. Both solve your error-detection-and-correction needs. -- --Dwight Ernest KA2CNN \ Usenet:...vax135!timeinc!dwight Time Inc.
