Sorry to start another thread about this, but the newsserver complained
about 8-bit data in header.

Except for the headers, the code _appears_ correct for use with DJGPP and
OpenWatcom. However, I would suggest using memset() to clear in_regs befor
calling the DOS interrupt. If REGS is setup the same as DJGPP or OW, you
can use out_regs.h.ah or out_regs.h.al. You could probably post the code of
in openwatcom.user.c_cpp or comp.os.mdsos.djgpp for more responses.

Thx for the elegant reply. I will go to reflect yours words and I will
find the house way ... =)
Thx for the help!
