For text output you should get the sources of the RHIDE text based
IDE for DJGPP and redesign it for your needs. Since RHIDE will work
for both, DJGPP and Linux, there should be no proting problems.
See http://www.tu-chemnitz.de/~rho/rhide.html for details.

Isolate your serial routines in one source for for DJGPP and one for
Linux. For Unix (incl. Linux) serial port programming see
