- Summary: Easy for printer to send info back to DEDICATED program
- X-Reader: NETNEWS/PC Version 2c
- Lines: 16
-
- There is nothing difficult about sending information back from a printer
- to a DEDICATED program. The program says to the printer 'Tell me' and
- then reads a serial bit-stream back from one of the handshake lines,
- perhaps using another as a clock and some form of interlock.
-
- Lap-link etc need special cables to connect the OUTPUT pins of one
- computer to the INPUT pins of the other, whereas the printer already
- has output drivers on the handshake output lines.
