Look in the DJGPP FAQ list (available as faq102.zip from the same place
you get DJGPP).  Chapter 18 there describes how to issue software 
interrupts from DJGPP programs.  (Btw, you don't have to allocate buffer
in low memory, if the 4KB-long transfer buffer provided by DJGPP is long
enough for you; this is also explained in the FAQ.)

For the description of the specific functions of interrupt 2Fh, look in
Ralf Brown's Interrupt List (available as INTER46[A-F].ZIP from any
SimTel mirror, in the msdos/info directory).
