I am using a Encore ENF656 external modem to answer remote calls.
Its initialization string: AT&C1&D2+MS=V22B,0,2400,2400
I am experiencing difficult answering calls: 25% successfull handshaking at 2400 bps.
The calling machine is configured utilizing same initialization string.
Why do this occurr? Is my modem poor quality one? Is it because I have ADSL in the calling and answering sides (noisy lines)?
When i use the calling machine to dial-up my ISP i can get connections at 33600 bps with no initialization strings. As you can see the dialing machine is OK, so I get more confused.
I will increase the points to 500 if I find a working solution.
