Using a Serial Interface Card (C82305 or 82306 )
To use a serial interface card (C82305 or C82306 ), see the sections
below regarding baud rate, handshake timing, and error handling. For all
other data transfer conventions, such as word structure and
communications protocol, see your interface card manual.
Selecting a baud rate
You can select from the following baud rates: 300, 600, 1200, 1800, 2400,
4800, 9600, and 19200 bps (bits per second). To set the baud rate, see the
bit-rate selection table in your interface card manual.
Handshake timing
When the unused area for data in the input buffer drops to 256 bytes, the
printer outputs an X-OFF code or sets the DTR flag to 1 (MARK) to
indicate that it cannot receive data. When the unused area increases to 512
bytes, the printer outputs an X-ON code or sets the DTR flag to 0 (SPACE)
to indicate that it is ready to receive data.
Error handling
When the printer detects a parity error, it prints an asterisk ( ). The
printer ignores all other errors, including framing and overrun errors.
