HELP! I have a MultiTech MultiModem 224E that I'm considering buying (it's on loan from Inland for two weeks). It's performed well so far but now I'm trying to talk to Ohio State (osu-cis aka cis.ohio-state.edu) to get some GNU stuff. The connection there through the Micom switch is going through Racal-Vadic modems which support Class 3 MNP. The 224E that I have supports Class 5. The connection is made, my modem blinks its 2400 light indicating that MNP is active. I request the GNU button as a test. The session ALWAYS hangs (no, not hangs up -- just hangs) at the same point, when 1536 bytes have been received in the T* file. I have heard that MNP and uucico do not get along together, but it seems to me that that shouldn't be true since MNP is at the "hardware" level below the "awareness" of uucico. Can someone expound on this? I called MultiTech technical support and they said that my switch settings as well as the parameters I send to the modem are correct. The ECM1 PROM level is 5.06 in the modem (which I was told is a few revs behind but is still ok). Could someone please help me on this? I talked to a comm person at OSU who said that since the connection is made and the conversation always hangs at the same point that it probably isn't any modem problem but perhaps a protocol problem. Although I agree, I still can't see anything else wrong. The only speculation I have is that one of the modems is buffering something or losing data (erroneously identified as flow control, perhaps?) so that uucico is getting confused. Oh, BTW, I tried turning off MNP via the &E0 parameter. When I do that, I get x's and vertical bars and other goop instead of the first "Ohio State..." message. ** PLEASE E-MAIL **. If you want to post as well, that's fine, but I'm behind on news and would almost certainly miss any relevant postings. Thanks again (and in advance) for ANY tidbits of information ANYONE has! If anyone wants to call me on the phone, feel free; I'm at either (312) 425-2529 or (312) 954-6512.
