Hi, there

	With WATCOM C/386 and PharLap 386|DOS-Extender, I failed to change
the interrupt vector in protected mode.  WATCOM C/386 is new to me.  So I 
am wondering if there's anyone be so kind to give me some help, I will will
sincerely appreciate that.

	I am currently using WATCOM C/386 with PharLap ASM|386, LinkLoc,
and 386|DOS-Extender.  And I  need to change the service routine of packet
driver interrupt.  First, I tried to use _dos_setvect and _dos_getvect 
routines provided in library.  But they didn't work.  I don't know how 
exactly they function inside the library, and doubted that if it uses DOS
INT 21h function 25h in the same way as in real mode (only AH=25h).  After
checking up 386|DOS-Extender manual,  It seems that INT 21h should be called
with AX=2502 and AX=2504 to do these jobs.

	So I wrote two routines in assembly language to replace _dos_setvect
and _dos_getvect, and linked them with the C portions, but still in vain.
What misstaks have I made?  Did I miss something?  Any suggestion or info 
will be appreciated, and please reply via e-mail.  Thanks in advance.
