  For example of a serial IO routine under go32, look under the serial.c
module of Ladybug 1.00 (ldbg100.zip.) The code is in plain C.

  You can:
  1. Use ANSI escape sequences (the sequnences can be found in most
     DOS manual, and example can be found in serial.c of Ladybug 1.00 --
     see above.)
  2. Use the routines declared under conio.h (gppconio.h ?)
  3. Uses int86, int86x calls to call BIOS interrupt 10
  4. Write directly to the screen, using the Screen... function calls.

  If the display routines deal mostly with serial IO, the best thing to do
would be using ANSI escape sequences. Otherwise, the routines under 
gppconio.h will do just fine.

Hope that helps,
Long.
