Hokay... After much testing, hex dumping, switching between Kermit and MDM730+, I have finally beaten the particular problem with my particular TAC when trying to download binary files with the Tops-20 MODEM program. Nuttin wrong with the MODEM program! (Well, nothing much.) Despite NOT having any "flow control" set on the TAC, and despite what the MODEM program is supposed to do to set up the TAC .. you MUST command the TAC to disengage flow control with: @@F O E @@F I E before the Tops-20 MODEM program can work. Yep, it takes BOTH flow controls like above - without either, you'll get the "Incorrect Record # in Header #n" message. Kermit, of course, has none of these problems SO LONG AS you have not SET flow control with the usual @@F O S or @@F I S Uploading still fails, with my system receiving sporadic NAKs - could be the hapless TAC's buffers overflowing, altho my Wizards of TACiness (got that from Europe) say it has the new improved 128-byte buffers, etc. So... Kermit for uploads, and finally MODEM for downloads. Thanks for all the help, guys. Regards, David Kirschbaum Toad Hall ABN.ISCAMS@USC-ISID
