Hi,
Is it possible to transfer files from a QNX computer to another QNX computer
using a parallel port?
Krupa
No.
The parallel port driver does not support bidirectional transfert.

Hey QSSL
This has been kicking around for over a decade now. Some 15 years ago I
used one of the crappiest OSs on earth called PC-MOS. It’s single nice
feature was that it did support networking over the parallel port. It was
reasonably fast and reliable too and over some long cable lengths (200 ft).

I realize that the parallel port is anchient technology but it would be nice
to use when its the only thing available.

hmm… probably smth like this:
file → print → scan → recognize → file ?
both printer and scanner works with paraller interface

Well it is possible to do this with a Parallel Port Zip drive in between,
but that is probably not what you were thinking of. I’ve looked at this
issue, and it would be quite doable using Net.dev however there are two
issues to be thought through. One is what should the cable look like.
This may seem obvious, but it is not. The only standards are defacto, such
as what Lap Link uses. Ideally one would use the data lines to move data
back and forth, but that would require a very careful protocol using the
control and info lines. That describes the next issue. There is not
obvious software protocol, although one could be cobbled together.

At one point one of my coworkers wrote a program to transfer files over the
parallel port between QNX machines on a lap link cable. I can’t remember
what happened with it, but Dev.par wasn’t running (for obvious reasons, it
would interfere, just as Dev.ser interferes if you write directly to the
serial port registers while it’s running for that serial port). At the
time, we only had 4 bits to work with over the parallel connection (in ECP
mode) so we had to do transfers 4 bits at a time instead of 8. I’m sure
there are other ways to do it that could be faster though. I also don’t
know if a hardware interrupt was attached to the port so it would handle
incoming data or not, but it worked pretty well.
Once it was prepared, you’d probably want to write some kind of program or
driver to run to handle the file requests so you wouldn’t have to knowingly
run everything.
Hope that helps

PS: Use serial port if you can, it’s much more fun and IMHO MUCH easier to
do stuff with

Try Net.fd on a serial port. It’s slow, it works and it’s brainless if you know
anything about networking QNX. If not, stick to qtalk/qcp.

There are, but probably not with a laplink cable.
