- Speaking of parallel ports, the one on the multifunction card I just got
- has a jumper for "TRUELY BI-DIRECTIONAL" operation where the
- "...direction is controlled by printer 'CONTROL' register as follows:
- bit 5 of CONTROl register
- 1 input
- 2 output"
-
- If I set the jumper for bidirectional operation, am I depending on the
- printer electronics to set that bit correctly? Do all printers do it
- correctly?
-
- Thanks and happy holidays.
