Hello everyone,
I might be entering a sub-sub-n iche here, but i'm trying to make the internal modem of my Model 102 work again.
I've connected it to a small home phone exchange (pabx) so that I have real proper vintage phone lines ( did I mention this would be of interest to a sub niche ?)
Problem is ; my model 102 does not pickup the line. A phone does, a good old USR 56K does, but it does not.
I have the proper grey/beige(rather pink now) cable
It's inserted in the right way. My init string (STAT) is starting with M, for internal modem
If I put a phone on the gray line, and "pink" in the PABX ; i can hear my dial tone, until I make the M102 dial, in which case the phone goes silent (which is normal).
But the PABX doesnt show the line as beeing picked up, I can hear the M102 pulse dialing in the void, but to no end...
It seems either the voltages are not right, or something is not working like it should.
I tried BASIC with "CALL 21200" (which pickups the lines) you can hear the relay click, but again, the PABX does not see that as someone picking up a phone.
I have an European M102 (could that be an issue ?) My "phone line" (vintage PABX) is a european (belgian) one.
However the M102 has been "upgraded" by a REX rom , that may be an issue (this upgrade was not my doing. I can barely use REX.)
It's unclear if, eventually, the modem section could need a repair (recap or smth)
Any help appreciated
