I found a cheap dial up USB modem on Amazon lately and thought it would be fun to test it out.

I've long since forgotten almost all the AT commands, so there's probably a lot left to do, but for starters it would be nice if someone with a POTS modem still attached to their mailer could test if it's possible to get a decent connection to 2:2/2, 2:20/0, 2:203/0 or 2:203/208.

I still have at least 4 Modems.

But rs232 -> Modem -> Pots -> ATA -> Isdn -> SomeBox -> Voip -> to
whatever is between my Voip and your Pots, is not likely to give a reliable
connection, if at all.

rs232 -> Modem -> Somebox -> Voip -> also does not work reliably,
probably because the internal pots line picks noise. Another factor is that,
the fancy protocols with fase angle modulation do to go well with Voip.

Reducing your modem speed to 1200/2400 Baud to pass through a 64kbit Voip is
an inefficient waste of bandwith and time.

But I am sure my ASR33 with a bell/103 modem may work. Now where did I put
that 20ma current loop modem?

Just kidding I never had such a modem, only one that had a rs232 input.
It weighed some 15 Kg was 19 Inch wide and probably 3 or 4 U high.

I've got an accoustic coupler here ...

The problem ... no phone around here fits.

I have a Dutch PTT model T65, that may fit, otherwise you will have to
look for someting older. The T65 is from the late 60's. Now that I write
this, I realise, that the model was probably introduced in 1965.

I just tried this with ifcico, and it seems to be working:

I tried a couple of times and got 9600/ARQ/V34/LAPM, 9600/ARQ/V34/LAPM, 14400/V34/NONE and 12000/ARQ/V34/LAPM/V42BIS, i.e. a little varying. But then I'm on VoIP here.

Thanks a million, Bj”rn. And yes, I'm on VoIP here too -- since about 15 years back, ;)

You're very welcome!

Yes, all the regular lines kind of disappeared back then... :)

I noticed one interesting thing about our connection:

09-May-2021 11:49:24 Establishing Hydra transfer protocol
[ 09-May-2021 11:49:25 Hyd: Other's AppInfo="ifcico,2.14-tx8.10"
[ 09-May-2021 11:49:25 Hyd: Other's HydraRev=01-Dec-1992, flags: C32

Hydra, a real blast from the past. The transfer protocol that came a decade too late... 8-)

:-D

I also noticed some Hydra timeouts, probably during modem renegotiations.
