I have a question that perhaps someone can answer. I was debugging my 2400 baud Microcom modem (AX/2400) to use on my unix-pc. Actually it was working quite well for about 3 weeks. Then it began getting flakey. About every few calls it does not restore to the non volatile memory settings. The DTR signal is set to &D3 which is necessary for the AX/2400 to answer in the AT mode. see Lenny's posting. After working fine for a few hours and resetting for each call like it should, it puts an arbitrary &D0 in the register. To trouble shoot, I call another system of mine with 2 modems attached, thru the internal modem by toggling. I then call back into ureka thru the AX/2400 to see if it will still answer the phone. That's how I can test the connection and the modem performance. PROBLEM: I was into system #2 thru ph0 and did a control-D to logout. When I toggled ph1 after hanging up, the CRT went Blip.... like normal. After that the phone manager no longer recognizes the .phdir file. I logged in as another user from the console and it didn't recognize that account's .phdir either. I renamed .phdir in my account, called up the directory, shift F2 and it makes a new .phdir and uses it but still will not recognize ANY of the original .phdir files in any users directory. I Tried them to check :-( DILEMMA: The file command still recognizes the .phdir file as an AT&T Phone account but the phone manager will not use the file. I desparately need to retreive the phone numbers stored there. I rarely use the phone dialer. I use the Directory function to store private business and private unlisted phone numbers. This is the only place I store them, electronically in a non- ascii file where the file can't be easily broken into. IDEAS ??? Please ! BTW: I don't recommend the Microcom line of Modems for use with the 3B1. They are NOT fully Hayes compatible. The documentation is poor. (no initialization or wakeup strings documented) There are 2 modes, SX and AX. SX is cryptic and is basically for VAXen etc. I believe that the intended use is as a uni- directional hookup. That's how they are used at the plant where I work. Single outgoing modems, 1 / tty "out" port and single incoming modems, 1 / tty "in" port. AX is supposed to be at fully AT compatible but is "partially compatible" at best. There have been some Microcom questions on the net but I never saw answers posted. Microcom is an expensive modem that you would be better off spending your money on a Trailblazer.(I wish I had) Perhaps the answers were posted but the distribution never reached my feed.(is that possible ??) Sic ....another nail in the unix-pc group coffin. pleasant platitudes, -- charlie
