Well, in OS/2 a COM device can be treated as a file, so the easiest way to 
use it is to open and use the COM device just as one would a file:
        ofstream modem("COM4", ios::out|ios::binary) ;
        modem << "ATZ\r" << flush ;
If you are making a door, then you need to find out how your BBS program 
passes the COM device to the door program.  With most decent OS/2 BBS 
softwares, the door program is spawned as a child process of the BBS program 
(the batch-file-in-a-loop system used by DOS BBSes is, in fact, *bad* design 
for an OS/2 BBS), and inherits an open file handle to the COM device, the 
number of which is passed as an argument on the command line, or in a door 
information file of some sort.  Even then, however, it's just a matter of 
associating a stream object with the right file handle.
