Switching to PPP.
And some seies of characters....
That means that your ISP uses PPP as the default connection protocol.
NO CARRIER
But I receive the result to be NO CARRIER .....Can you please tell me
what could be the problem...
Because the PPP handshake timed out.
With the same ISP account i am able to dial and connect to internet
using KPPP dialer....
Because you used PPP to connect.
Once the dial up is over with minicom,, I can integrate the AT
commands
in my C program, to Read and write from/to Serial port, ( Hope this
works)
If your program speaks plain serial protocol, then use another machine
that speaks the same protocol. You can use another linux machine (with
another modem) to connect to; all you need to install is mgetty
package. This daemon would detect whether the incoming call was using a
PPP or serial connection. If it was PPP, then mgetty would run pppd. If
it was serial (ie: from dialing-out minicom), it would run login (the
program that gives you the login prompt).
