- Chip - a question if I may.
-
- A few years back when I had some long documents that weren't
- printing to the end because the spooler interface program
- exited and reset the ports, I put a line in rc.d to run an stty
- on the port at boot time, and then sleep for 5 minutes,
- then run again.
-
- This worked fine with the spooler, and I had to do the same
- thing a year or so ago on a Specialix port that was running
- Nexus Scripsit and FilePro. The Scripsit had it's own
- interface that I couldn't seem to get right. Don't know for
- sure, but the rc.d thingy fixed it - had to get the
- rstflow/ctsflow set for a strange printer.
-
- Would this concept work for the device that is printing
- directly to the port? My mind says yes - no - yes -maybe
- -maybe not.
-
- Or to word it another way, when writing directly to the port,
- are all the settings that stty initiated ignored?
-
- -
-
- And I agree about the aps that write directly to the port. I
- had to give a person the bad news that he was stuck with his
- machine and hardware, because the software was writing directly
- to a multi-port board long discontinued. I couldn't figure
- out what was happening at first when I found that all the
- terminals were running but no ports were enabled :-(
