VxComm 009
back
Q:
Will the VxComm Driver allow the SetCommState( ) API to dynamically
change the baud rate, data bits, parity and stop bits?
¡@
Ans: Yes. In the Win32 environment, users should call the
CreateFile(
) API to open the COM port(s) and then use the SetCommState( ) API
to configure it.
¡@
Third-party
tools may provide an OpenCom( ) function for the easy opening of
COM ports. In actuality, they must use the CreateFile( ) and
SetCommState(
) APIs to implement these kinds of functions.
