Re: (Xmodem ) "Modem command state not present" pr

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?
