Does anyone have any code or ideas on how I can read and log the
information written and read from the IBM-PC/AT's DMA port 0x0E.
I have an ALLOY TIP40 tape drive that talks directly to the DMA port to
control the drive, and would like to rewrite the interface for the
program in C myself to add some useabillity to it. I particulrly don't
care for they're interface (IMO).
I had an idea of using a TSR to constantly monitor the port and log the
info to a file (like give the TSR 60% of the time slices and the rest
to the tape program.)
I have dis-assembled the program itself, but being very weak in
assembly language, I didn't get much out of it, other than it was that
port on the DMA. I cant tell what codes they are sending to the drive
to control it.
Any Ideas?

Recently there have been posted to comp.lang.c a number of the sort of article to which this is a followup. Although ports on IBM PCs can sometimes be manipulated via C routines, such articles do not belong in this newsgroup. Please use IBM PC specific newsgroups for IBM PC specific questions. (The same goes for Unix specific questions such as `how do I read a raw V6 filesystem off my old RK05 platter?'.) -- In-Real-Life: Chris Torek, Univ of MD Comp Sci Dept (+1 301 405 2750) Domain: chris@cs.umd.edu Path: uunet!mimsy!chris
