It's the standard. Is there some reason why you can't do this? I do not want to use "uucp" because the it requires disk space for spool files and human intervention to set up and maintain. In the next couple of years we expect to have over 2000 microcomputer/workstations on campus. Many of those microcomputer/workstations will be Unix systems with modems and terminal emulation software. The overhead in maintain uucp links with 1000+ workstations would be to high. So what I am looking for is a "xmodem" (cf. MDM7xx) program written in C that will permit a user on a Unix system (eg. a Unix microcomputer) to dial out to a remote Unix system, login to a remote Unix system (via terminal access dial-up lines), execute a remote "umodem" program to start a file transfer, escape back to the local program, and fire up the local end of the file transfer.

From: William C. Wells <wcwells%ucbopal.CC@Ucb-Vax.ARPA> I know someone who would like to dial into our Unix system and from another Unix system (using the Unix "cu" command), then use a modem program to transfer files. We have the 4.2 BSD xmodem (from UCSD) on our end. Does anyone know how to do this? Some problems encountered so far: Executing xmodem on the answering system and umodem on the originating system from within "cu" does not work. xmodem, tmodem, umodem, and uc all appear to be programs for the answering Unix system. "cu" (version 7) appears to be able to redirect output or input, but not both to the same program. I suspect that "cu" needs to be called from the the originating modem program to establish a terminal mode with the remote system. Does anyone have a modem program that will do this? Or does anyone have a Unix modem program that has a terminal mode? Bill Wells wcwells@Berkeley.ARPA ucbvax!wcwells wcwells@ucbjade.BITNET

From: Lauren Weinstein <vortex!lauren@RAND-UNIX.ARPA> Both umodem and the C versions of kermit already have "connect" modes for making outgoing connections. Neither directly support automatic dialing, but this is pretty modem specific and trivial to add for any given case. Or, if you prefer, you can always dial out with "cu," suspend the connection, and then use umodem or kermit for the file transfers as you choose. Such procedures would probably be adequate for the sorts of "occasional" file transfers you apparently consider likely within your "network." --Lauren-- P.S. If you plan to use umodem, you'll have to look around for the version with the connect feature. There are a multitude of different versions of umodem that people have spawned off from my original code. So many, in fact, that I no longer officially support umodem in any manner. --LW--

Where is there a description of the UMODEM error messages that go into the LOG file? Thanks John
