A number of people lately have been asking about PD file transfer utilities for UNIX ie. Zmodem, Xmodem etc. I have a set of PD programs that I use on our SUN/4 (Zmodem, Ymodem, Xmodem). If anyone wants them send me a message and I will mail them out in a uuemcoded-zoo. The include source in C and full documentation so the file is kinda big. Marc Mousseau ummouss2@ccu.umanitoba.ca

While on the subject of X, Y, and Z modem protocols, has any one ever seen/used
any of these under CMS on an IBM mainframe? Kermit is terribly frustrating
and something like this would be helpful to many I'm sure.
Any info is much appreciated, thanks.

The problem with transfering files to and from IBM mainframes is that characters on the IBM side are not stored in ASCII format but trather in EBCDIC (pronounced "epsodic") format. The result is that only a character based transfer, such as Kermit, can do the job.

The problem with transfering files to and from IBM mainframes is that characters on the IBM side are not stored in ASCII format but trather in EBCDIC (pronounced "epsodic") format. The result is that only a character based transfer, such as Kermit, can do the job. This happens only if you request character set translation to occur. If you do a binary transfer, you should be able to transfer .ZOO files and such as unformatted binary files under CMS... Since some protocol converters can become ``transparent'' (as if done with CMS Kermit), it seems reasonable that someone could write a zyx-modem program for CMS... ...tad

When it was in transparent mode it would pass characters transparently but still required an end-of-line character; this makes sense to me because IBM mainframes talk in half-duplex and need some indication of when to turn the line around. Kermit uses an end of line indicator; I know xmodem doesn't, am fairly sure that ymodem doesn't either, and I would bet a very small sum of change that zmodem doesn't since it seems to have descended from the others. I think this all means that you can't use [xyz]modem with IBM mainframes without a new form of protocol converter or actually re-programming the current protocol converters. Maybe someone who knows more about this than I can explain better... --> steve -- Steve Wahl Northern Telecom, Inc.
