set connection to a modem

[s m]

thanks chris

ppp is used when you want connect to internet via modem. i just want to
config my modem by AT command.
when my ppp.conf file is empty, i can talk to my modem so this config file
do nothing what you want talk to your modem.

if i want to talk to my modem by a specific speed, which config file should
be changed?

please let me know if you have any guidance.
thanks
