I suppose it depends on the phone, the network, which codec, and what kind of noise cancelling was being used. Just yesterday I was on my cell phone and the alarm tone from my UPS was nice and loud to me, but the person on the other side couldn't hear it at all. On May 25, 2017 2:03 PM, "Kurt

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

Normal headphones are TRS. Normal headsets are TRRS. Did you try with a TRRS connection? On Thu, May 25, 2017 at 1:16 PM Kurt McCullum wrote: > 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

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.

I think for 110 and 300 BAUD it would be fine, where audio frequency-shift keying was used. But any of the higher BAUD rates that use PSK or QAM wouldn't make it past the audio/data compression used in cell phones. On 5/25/2017 12:50 PM, Andrew Roach wrote: I thought cell phones couldn't be

I thought cell phones couldn't be used for BBS connections? If that works, I very much want to explore it more. On Thu, May 25, 2017 at 11:36 AM John R. Hogerhuis wrote: > Interesting. I would have given that a low probability of working. Well if > that works you'd think a

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? -- John.
