I just received my OKI 320 Turbo today with the serial card. Set the printer up for 9600, 8N1 and hardware handshake. Tested it on one of my PCs with good output via serial. What is the setup needed within the Altair Clone to support serial printing on port 2, using CP/M 2.2b and MBASIC-80? Right now all LLIST and LPRint go to port 1 only. I have configured the following:
"6) Admin Menu" --> "2) Line Printer Controller" --> "1) Enable LIne Printer on Serial Port 2" The Line Printer Controller shows Current setting: Line Printer Enable on Serial Port 2.
The 3) "Serial Port Menu" shows that all my serial ports are setup to 2SIO at 9600 and 8N1. I have switched port 2 to SIO at 9600 8N1 and back.
I have placed a serial line monitor on port 2 and see good handshake and send reaceive data voltages present on the correct pins. Running an LPRINT or LLIST from CP/M MBasic-80 only gives results on port 1. Port 2 nothing.
So what simple thing am I missing?
