I am attempting to hook up an LA75 serial printer to the A2000 parallel
port. I have the LA75 in other mode at 9600. I copied the CBM
MPS1000 driver and selected in perfs. When I started this I did
not realize that the cabling would get so complex. But, this is
how it currently stands.
A2000 parallel port
1 cable DB25 to centronix
2 Parallel to serial converter
set to 9600, 8 data bits, 1 stop bit, parity inhibit
3 Male to male gender changer
4 Stanadard DEC cable to hook to terminal printer port DB25
LA75
set to 9600, 8-None, protocol: other
Emulation settings
Paper bell out : On
Slashed zero : Zero without slash
Auto LF on CR : No auto LF
Active char set : Graphics set A
Auto CR on LF : No auto CR
Power-up density: Draft
LQ or NLQ : Select NLQ
I attempt to do a COPY file PRT:
I get a long pause and requester that tells me to check the printer
cabling.
Questions:
1. Does anyone have a serial printer hooked to the parallel port
in any way?
2. This should be possible shouldn't it?
3. Any help with what I may be doing wrong would be greatly
appreciated.

| 2065.1 | LA210 failed also | VTHRAX::KIP | Mon Jan 02 1989 12:53 | 5 | |
For the record, I tried doing this with an LA210 and my A1000.
I had the specific parallel to serial converter made for the LA210.
I did not have any of the printer emulation modules available for
the LA210. It just would not work.

| 2065.2 | Good news and bad news | CSOA1::LEN | David M. Len | Mon Jan 23 1989 16:46 | 15 |
First the good news.
I was able to get the printer working with the parallel to serial
converter. I seems that the default setting for the converter is
for DCE not DTE. Therefore, null modem cable allowed it to work.
Now the bad news.
The LA75 uses Xon-Xoff for flow control, which is not seen by
the converter so data over-runs occur. I think if the LA75 supported
CTS/RTS it would have worked without a problem.
So I am now going to see if the store will let me return the converter
back. And I guess I will get an RS232 A/B switch.
