Hi all,
I want to permanantly modify the settings of a modem that I have one my
machine called "Standard 28800 bps Modem". I want to set the baud rate
to 38400, data bits to 8, parity to none and the stop bits to one. So
the questions:
1) Will the API functions GetCommState and SetCommState allow me to
permanantly modify these settings, ie when I call close handle will they
remain as above?
2) What do you need to pass to the CreateFile parameter LPCTSTR
lpFileName, // pointer to name of the file
this is the first parameter, for comm ports it would be COM1.
Many thanks
Joe
