![]() ![]() My best guess is that this is because the USRs actually transmit too loudly on the line, and actually rely on the phoneco to attenuate it (or in many cases just clip the tops/bottoms off all the waveforms resulting in a shitty connection). (56K not supported with neither side digital) USR chipset based modems below 56K, however, will often end up in an endless spiral of retraining to lower speeds. With most modems, this will result in the highest possible connection speed, up to 33.6 every time. On the "answering" side use the ATA command to pick up. You can issue it as a separate command or put it in your dial string, i.e. On mostmodem chipsets ATX3 will disable the dialtone detection. The thing is by default it looks for a dialtone and will return a "NO DIALTONE" message when it doesn't find one. You can connect two modems together just fine. ![]()
