I just had to look for that V.21/V.23 acoustic coupler and yup, i still have it. :) But shouldn't just about any analog modem still be able to talk V.21 too? Or do the recent ones no longer? (Could be you have to send some command to allow non-error-corrected connections.) >The code can be found at: http://phk.freebsd.dk/V21/ > >Poul-Henning >(who feels a little bit nostalgic working on 300baud again) I wonder if i still have that 1200/75bps atari sio driver somewhere that i had to hack for V.23... (yup that was an asymmetric standard, and the uart had only one clock for both directions so the 75 bps had to be done in software.)
