: There are numerous ways of initializing a serial port with 'C'. My standard
: method is to directly write to the UART addresses. A more commonly used method
: is to use a library function such as `_bios_serialcom`. Most `C` compilers for
: DOS have this function or one that is similar. If you wish to write directly
: to the port addresses, the proper function to use would be 'outp','outport`,
: `outportb', etc., again depending on the compiler you are using.

If you want all the hardware details of the serial port, of course the
hardware spec (e.g. for National Semiconductor 16450) will have all the
"hard" :-) details.  Borland is offering a sample driver (source) from their
bulletin board, (408)439-9096; it is called SERIAL.ZIP.  I have a shareware
product called SERIOUS which is a DOS installable device driver for 
serial ports, and offers a C/C++/ASM interface to the application programmer.
It is available in the net ibm archives, and various boards elsewhere.  If
you want to try it, and have trouble finding it, please let me know.
