I'm confused. DJGPP does not have termio.h, it has termios.h. What
version of DJGPP are you using?

Correct. The DJGPP termios implementation currently only supports the
terminal device. It does not support the serial port (or any other
devices). The recommended way to add such support is to use one of
the available async communication packages in conjunction with the
DJGPP Filesystem Extensions feature. The DJGPP FAQ has pointers to
several serial communication packages in section 22.3; the Filesystem
Extensions are described in the DJGPP library reference.

You mean termios.h, right?
This is the largest baudrate because that's what most termios
implementations support. However, once you add serial port support to
termios, you can easily add more Bnnnn constants and support them as
well.

If you use the Filesystem Extensions, the sources will be left
unchanged. All the magic happens on the library level; the program
doesn't know anything about that.
