I just got a couple of spankin' new USR V.34 internal 28.8K modems and put them in both a 1.1.5.1 FreeBSD and a 2.05R box. I have used the external 28.8K's with no problem for a year on both of these systems, but the internals are acting a bit strange: 1) About every other time a V.34 modem will call into the FreeBSD's V.34 internal sportster (using plain getty on that..), the FreeBSD modem will hang up on the caller. The banner page will get about half printed, and then the calling modem will hang (due to loss of loop/carrier). A check into the status registers of the calling and called modem reveal that the call-ed modem hangs up because it receives a DISC, but the call-er modem says it hangs up because of loss of loop/carrier. 2) Taking getty out of the equation, and just attaching cu or tip to the line to answer the phone cures this problem... every time a connect works fine. Cant do much just connecting without getty, so that's just a test condition, not a solution. Does getty mess with the serial line settings upon answering the phone?? It shouldn't, as I have tried setting the inital and lock state devices up locking crtscts, baud rate, etc... 3) Using these internal modems (USR v.34) to call out to other 28.8K modems connected to FreeBSD boxen (an external USR 28.8, a Supra 28.8K, V.34), I also get disconnects (locally on the calling USR V.34 internal), about halfway thru banner pages. So basically, these new USR V.34 internals are flaking out on me, but only when being used in a FreeBSD situation (calling, or being called), and only at V.34 or V.FC connect rates. Once connections are made, they are fine, but that's only about half the time I try to call! I have called USR on this 3 times, trying to get them to help, but some tech droid always tells me they can't help because of my 'non-standard' operating system. I even had a guy call into my modem to demonstrate the problem, but I can't seem to convince them that their firmware is flaky or etc... One more detail, these modems are actually V.34+, and say they can do 33.6K (and do pretty high like 31.2K when connecting to each other), but even disabling that feature doesn't change matters. Anybody out there have any problems with these things?? If not, how about some words of wisdom to give USR so they will further investigate/fix the problem. Thanks much, Troy
