I wish to write an MFC program that sends/receives data from COM2.  I know i can't use the inp and outp calls found in dos programs.  Are there any API functions that I can use? Can I use CFile to open and read/write to a serial port?
I would appreciate code snippets.  Many thanks!!!

Use Win32 Communication Functions.

The following functions are used with communications devices.
 
BuildCommDCB  
BuildCommDCBAndTimeouts  
ClearCommBreak  
ClearCommError  
CommConfigDialog  
DeviceIoControl  
EscapeCommFunction  
GetCommConfig  
GetCommMask  
GetCommModemStatus  
GetCommProperties  
GetCommState  
GetCommTimeouts  
GetDefaultCommConfig  
PurgeComm  
SetCommBreak  
SetCommConfig  
SetCommMask  
SetCommState  
SetCommTimeouts  
SetDefaultCommConfig  
SetupComm  
TransmitCommChar  
WaitCommEvent  

There is a sample "Comm: Communications Demonstration" that comes with Win32 SDK or Visual C++.
