CAUSE: PC serial card uses IRQ4 instead of IRQ3.
SOLUTION: Reconfigure serial card, use different
serial card or different terminal emulation program.
PROBLEM: PRINTS GARBAGE
SYMPTOM: MISSING CHARACTERS
CAUSE: Incorrect cable type.
SOLUTION: Check manual for correct pinouts
between PC and Model 24, and between Model 24
and printer. Check handshaking. A way to check is
to force an error condition at the printer (i.e,
remove paper tray from laser printer or turn off-line
with power still applied). Send print job to printer.
If printer port LED goes off, you can conclude no
handshaking was done between the Model 24 and
the printer. On serial ports, program Model 24
configuration to match handshaking (i.e. you must
be using CTS/DTR or XON/XOFF for both Model
24 and printer). Also check pin 20 of printer to pin
5 of Model 24 if connecting in serial or pin 11 to pin
11 if connecting in parallel for continuity by using
an ohm meter to check resistance from end to end.
CAUSE: Cable length.
SOLUTION: Use shorter length or higher-quality cable.
Parallel cable should not exceed 15 feet. If using
serial cable, length should not exceed 150 feet.
CAUSE: Configuration problem.
SOLUTION: Check baud rate, word size, stop bits and
parity on serial ports. It is best to be at 8 word size
and no parity.
