 | | That should be enough to, in the meantime, if I find someone interested that has more coding capability than a turnip (which is about my level) could code something up to work as a standalone piece of software. |
 | | FWIW, for US anyway, traditional TDD's use 45.45 baud, 5 data bits, no parity, one and a half stop bits (weird, I know), 1400Hz and 1800Hz FSK, I'm assuming, but haven't found any information to support for sure, that the 1800Hz is a 1, and 1400Hz is a 0 in the transmission. |
 | | Most of this information, I would assume, is included in the V.18 recommendation, and probably more as the V.18 recommendation is inclusive of many of the international standards as well (50 baud rather than 45.45 baud is common from what I understand). |
