Hi, Brent.

BR> There really is something you could do with a 100-foot long serial

<snip>
BR> headache. Yes, most of those big daisy-wheel printers had both a
BR> serial and a parallel interface. Remember, with those old daisy-wheel
BR> printers, we're talking rather low numbers of characters per second,
BR> not pages per minute.
I just recalled that my HP-500C Deskjet has both serial and parallel
inputs. Hmmmm....
Used to have an old 300 bps Decwriter, which was handy for printing
labels & such and any wide-carriage printing I needed to do, reports &
such. Yes, they are just a tad noisy. <g> Had two in the EPA auto
emissions labs where I used to work, running continuous paper logs of
the activity on our minicomputers that processed data from the test
sites, and some of the sites had similar machines used as terminals.
With XT's being as cheap and available as they were, Decwriters & such
didn't end up making much sense as terminals, except in the sense of
being Already Paid For. But it seems to me that the runs to those
machines were mostly very long serial cables. And from my reading on
such years ago, 100 ft was the suggested maximum length for serial
cables. Haven't tried one that long, so I can't swear to functionality.
I have a little five-wire serial null-modem cable I built myself, not
sure on length, maybe 100-some feet long, sitting next to my OLMR
machine here. Used to use it for passing files back and forth with the
BBS machine. Used 6-wire phoneline, send-receive-ground wired through,
CTS-RTS wired through, DTR and DSR are jumpered on either end. The
software I used most, though, only used three wires and (I guess) some
software handshaking. No problems I could detect.
I also have a 50 ft straight-through cable with DB25 connectors. No
idea how many leads are actually wired -- I'd guess the basic nine,
anyway. 100 foot cable? I simply don't have anything 100 ft away I
want to connect to. <g>
