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
