The C82305✽/C82306✽ serial interface card
To use the C82305✽/C82306✽ interface card, see the sections below to set
the correct baud rate, handshake timing, and error handling.
For all other data transfer conventions, such as word structure and
communications protocol, s ee the C82305✽/C82306✽ interface card
manual.

Selecting the baud rate

You can select from the following baud rates: 600, 1200, 2400, 48 00, 9600,
and 19200 bps (bits per second). To set the baud rate, see the bit-rate
selection table in the C82305✽/C82306✽ interface card manual.

Handshake timing

When the vacant 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 vacant area for data in the
buffer increases to 512 bytes, the printer outputs an X-ON code or set s th e
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 ov errun errors.
