Re: modem help needed

[Manish Kumar Arya <manish_ipx@yahoo.com>]

hi
   this is my second mail regarding modem problem.
i have made lil progress in this
  Lawson told me that i should recive "CONNECT" from
remote system(modem/fax machine).I did tested my
program by dialing to ISP and got "CONNECT" and there
after "Login" and then "Password". its worked with Fax
machine too, I was able to get "CONNECT" from fax
machine.
   but i m still not able to find way to communicate
with normal phone calls (voice calls).
   i have found a set of voice commands on net.

as per this doc i did set modem to voice mode

AT+FCLASS=8 
AT+VSD=128,100
AT+VGT=128
AT+VGR=128
AT+VRA=100
AT+VRN=10
AT+VCID=1
AT+VNH=0
AT+VIT=0
AT+VDR=1
AT+VSM=141,8000
AT+VLS=1
then at last i dialed to a voice phone no.
ATDT238470
and got "OK" reply from modem
still wondering what to do next to start reading data
on phone line

pls help
