i set speed 115200 with kermit, the problem now is the modem not respond to "at" commands, next i set the speed to 19200 but the modem dont respond to "at" commands, i use the tip program for configure the modems (like kermit) but i cant configure the modem to factory at&f, how can i do?. With other modem, i use the "mgetty -s 115200" in ttys file and it works (from reply Jim Bryant <jbryant@unix.tfs.net>) and the comunication is most faster now we have an average round-trip (with ping) of 140 ms in the past the average was 230 ms (betwen the server and the interface pppc00.mydomain --> /dev/ttyc00). the question now is why if the modem works well with mgetty and 115200 of speed when i set the speed with kermit to 115200 the modem is'nt work? thank you for your replys Saludos Alejandro At 17:20 23/01/98 -0500, you wrote: >The modem must be convinced to communicate with FreeBSD at the >desired speed.
