A change de FlowControl property from fcNone to fcDtrDsr and the problem has fixed...
BUT now I cant get the response of command. I send a command and the state is forever msATSent ... forever waiting a response for modem
code:
Delphi-Quellcode:
xModem1.OpenDevice;
xModem1.EntercommandState;
xmodem1.SendCommand('ATDT1234');
showMessage('before start wait');
at:=xmodem1.WaitForAT(0);
showMessage('after wait'); //NEVER execute code at this point. apear that never get a response for modem
xmodem1.exitcommandstate;
xmodem1.closedevice;
anybody have an idea?
