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

https://www.youtube.com/watch?v=drpvYSlczyA&list=UU_HRlflCd1ogZBmCu3_Mr0g&index=2

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.
