Last year (Sept. 88) we purchased some TB+ modems along with our other half in England hoping to get great e-mail service. It worked great for about 2 or so months and then suddenly we started to really eat it on performance. We'd call and sometimes not even get carrier, or connect and loose the line before the uucp login could succeed, or just drop in the middle of a transfer. Funny thing is that, through all of this, if the Brits initiate the call, they get through and can get all of the work performed just fine! Several things have happenned since we first set up: our ROLM system was "upgraded" with more capacity for extensions (no flames about going through the ROLM, please -- we tried a direct line with little or no better results); our long distance carrier (unknown to me) started switching over to "One plus dialing" (apparently, the ROLM system, invisibly except for time, was calling a number and entering an access code whenever we dialed a long distance number). Now I can code the ROLM to give me an AT&T trunk instead of our normal carrier (of course it all really goes through AT&T anyway), and that seems to have helped but not enough. One thing that is really strange is that when we connect, we just get CONNECT, not CONNECT FAST, not CONNECT FAST/COMP/UUCP (which is what we really should be getting). Yes, we have Q0 and X3, so we should get the whole thing right? We call other systems in the U.S., the only difference is the number, and here we get FAST/COMP/UUCP! I'm sure they have their registers set correctly at the other end to enable COMP/UUCP. In any case, the FST light on the modem is on, but the modem doesn't give the extended result code it should. I've talked to Telebit and need to talk to them some more, but if anyone has any thoughts that might help (we're playing with S120 and S36) I'd like to hear them. -- Randy Kunkee Ferranti International Controls Corporation 12808 W.
