Yes. I actually took a four conductor 3.5mm plug and tried all sorts of wiring
configurations. My cell phone tests for a load and switches its configuration
based on what it thinks is installed. This can be verified by a small icon on
the phone which appears when a handset or headset is attached. When I plugged
in the novelty headset, it worked for talking. But my 102 would spew garbage
when a connection was made through the acoustic couplers and the handset.
I'd love to see it work, but I'm not sure how useful it would be.

Normal headphones are TRS. Normal headsets are TRRS.
Did you try with a TRRS connection?

I tried this exact setup more than six months ago and I could not get it to
work. Perhaps my novelty handset wasn't loud enough. My couplers work with a
land line phone just fine.
It's really cool to see someone who actually got it working. I'd be interested
in knowing the make of the handset. But as John said, a direct audio connection
'should' work better. But my cell phone wouldn't allow it because a direct
connection didn't provide the load that an earpiece and mouthpiece provide so
it assumed I had plugged in a set of headphones. It was a frustrating test. I'm
sure someone with more electronics skill that I have could figure it out.
All that being said. The end result is a 300 baud connection. That was one of
the driving reasons for putting the virtual modem mode into mComm for Android.
That way I could 'Dial' into any BBS through my phone using a serial
connection. The connection speed is 19200. Of course the screen limits the
useful speed to about 600 baud.

I thought cell phones couldn't be used for BBS connections?
If that works, I very much want to explore it more.

Interesting. I would have given that a low probability of working. Well if that
works you'd think a direct connect cable would be even better.
Opens up a whole new possibility for remote usage of Model Ts.
Does anyone know what would be needed for a direct to headphone jack connection?
