after the "AT A" command, the modem starts trying to connect. Any other keystroke before it gives you the "CONNECT" message will abort that. If you don''t get that message, you aren''t connected.

How appropriate. You fight like a cow.

Hi
so, it isn''t working.
After we used "at a" it stops ringing, , but after ca. 3 minutes, the modem returned to normal mode, and destroyed the connection. there is just an o at the gsm modem.

thx
