I'm running DOS 6.21 and want to use INTERLINK to transfer files from one
system to another.  I would also prefer to use the parallel ports instead
of the serial.  The dos manual calls for a "bidirectional parallel cable".
No mention is made of how this cable is to be wired.  Can someone tell me
what the pin to pin connections are?  I'd like to make one.  Thanks!

I don't know what the pinouts are, btu I was able to find this kind of
cable at my local CompUSA for about $6-$7.  Considering that parallel
cables have a *lot* of pins to wire up (for bidirectional use, you're
probably looking at at least 17-20 wires), it would probably be a lot
less work to just buy the cable.

However, I think I have a pinout for a similar cable around here somehwere.
If you really want to build your own cable, I can probably dig it up
and type it in.

I went out and bought one from CCS a couple days ago.  I guess I can
ring it out if I really want to know.  (I'm a little surprised that
this information isn't give in the DOS 6.XX manual!)

Wouldn't the cable be just straight-through? 

I tried that: No go.  Looking at the signal directions, I can see why.

It's many years since I tried INTERLNK
but I /think/ it used an ordinary PLIP
cable...
