4. OIT3250 Special Features
4.1. Connecting to Printer
The second serial port of the OIT3250 is also used to connect to a serial printer.
This feature enables the OIT to print messages. The OIT 3250 uses XON/XOFF
software handshaking to communicate to the printer. The communications
parameters (ex. baud rate, parity, etc.) used are determined when the OIT is
configured. Consult the OITware-200 manual for more information. Connection
to the printer varies depending upon the pinout of the printer. See Figure 11 for the
OIT Port 2 pin assignments.
