The faqs.org says 9600 baud is the going rate, yet when I tried to setserial, my keyboard fubarred and I had to reboot.

?! why would that happen ? Maybe you are trying to write to the wrong port ? I do not know what the tty keyboard looks like on a Mac but if you tried to configure that or a UART (Z8530) shared with it then it would explain it.

Yes... are you saying that the keyboard and modem on the macos are split in fact at a physical outside-the-box level, and represented as separate devices but handled by the same 8530. What I saw was evidence of a buffer overflow?

You also want to see the manpage of stty wrt. settings for manual testing like buffering etc.

If the printer is post script then the raw text you send will cause the interpreter to curl up and die. Try to send a short ps file. Like man man -Tps >/dev/wherever. Even this may not work if the printer requires JCL control to enter PS mode or xon/xoff handshake. You have to find some info on your printer. A captured printer file from another Mac with the same printer would help a lot. Have you tried to look at the printer's answers ? As in cat </dev/theprinter|od -a ? Try this after turning it off and on again. You can test the port completely and maybe talk to the printer for testing using minicom, since it is serial.

Thanks for a gold mine of suggestions! The kermit interface worked. I "set line /dev/ttyS1", connected and nothing came out. I returned to the kermit prompt and "set speed 9600" (it defaulted to 38400). That worked. Now all I need is an /etc/printcap entry and I'm done. Unfortunately, I don't know the printcap syntax well. I guess I'll have to learn. -- The Toronto Linux Users Group.
