Hello,
Looking into a two computer "LAN" for my office has gotten me
thinking about the possibilities for cheap short distance
communications, and while I'm planning on buying a 115k baud serial
lan (Desk-Link TM), I have become interested in the potential of much
faster parallel communication. Unfortunately, I have been having
trouble finding serious disscussions of the parallel port in print;
most books give about one page to the "printer port" and tell you to
use DOS or if you are feeling unfettered the BIOS because PC printers
are slow. This is not entirely satisfactory. Some trial ins and outs
have assured me that the printer data port 03BC for lpt1 is indeed
read/write and that the printer control port 03BE can be written to
and read from, although the results are not quite what I might have
expected. I suppose that at this point I could work something out,
given some time and a break-out-box, but I would rather do it the
"right way" and get some documentation on the hardware before I start
hacking. Hints, directions or other forms of help would be greatly
appreciated.
If I get generally useful mail, or if asked, I will summarise.
Thanks in advance.
Ciao,
Tom
