A colleague wants to transfer a file from the CP/M side of a Dec- Mate II to a VAX running 4.2bsd Unix. The VAX has UMODEM, XMO- DEM, & KERMIT available. He says he's tried MODEM730 & MODEM740 he got from a BBS that are supposed to be configured for a Dec- Mate II but cannot get them to work. They work OK in terminal mode but will not transfer files correctly. Any suggestions? --Gerry MILNET/ARPANET >-------------------- key@nosc.arpa ihnp4 \ akgua \ UUCP decvax -------------!sdcsvax!noscvax!key dcdwest / ucbvax /

Gerry - We have been using various file transfer protocols on various host machines and, so far, I am pretty impressed with Kermit. If you can get your hands on the CP/M version, I think that you might find it pretty good. If you can't find it locally, it can be FTP'ed from Columbia-20B. Let me know if you need any help.

I have done most of the work on the DECmate MODEM overlay, so perhaps I can help. You should first check the overlay file to see if it really is a version that has the most recent DECmate code in it. The problem is that the 6120 (PDP-8) processor in the DECmate II handles all the I/O, and in particular it grabs any XON/XOFF's (^S/^Q) and does its own flow control without passing them on to the Z80. It is possible, however, to command the 6120 to not do this and pass thru everything. This is what the overlay does, in the initialization subroutine. You should look at the source code in the overlay that you have to see if that feature exists and is enabled. If you do not have the most recent overlay, which is called something like M7VT-4 (or higher), you can get it from SIMTEL20 or DEC-MARLBORO. Incidentally, I have noticed that MDM730 and higher running on DECmate's seem to have a problem with passing thru function key escape sequences, in particular the direction arrows. I think it's some kind of timing problem, but I haven't pursued it. I don't *think* it affects file transfer. Personally, I always use Kermit. %Walt -------
