Ive got a prentice Star acoustic coupler modem that I am trying to get connected to my dial up mgetty terminal.
I have 2 combinations set up using Proterm 2.0 running VT100 emulation
the first setup works perfect
1> micromodem IIe on slot 2 N81 None 300 baud
Here is the video https://www.youtube.com/watch?v=Oq3owPgqjEU
the second setup is
2> superserial ----> toggled for modem and non smart modem in slot 1 N81 None 300 baud / full duplex / originate

scenario 1 works perfect
scenario 2 connects fine at 300 baudshows a different encoding on the screen than one would expect. its not garbage and is
predictable. It seems I can log in and the mgetty host can red what I type. The characters echoed back are not the same as those I type.

Ive edited the second movie to use an HD version
Im adding two more movies showing that dialing minicom instead of Mgetty , shows the modem to work nicely
Here is a terminal session with the star acoustic coupler dialed into minicom

Here is an xmodem file transfer from the apple II to minicom

Guess I had to take care of this one myself.
The modem needed to be recalibrated after many years and the circuit was retuned

jrubin,
I just finished watching the first two videos.
Video 2:(about 3/4 of the way through) you started receiving the "Repetitive" code.
It looks to me like it was asking for some sort of input from you.
Maybe it was asking a question and wanted an answer?
I'll have to watch the others to get a full feel for whats happening.

Update:
Damn. Looks like you about have it licked J.
Kind of hard when you don't have a manual to help you.

I used fldigi to recalibrate the modem tones
Ok I'll bite.
