The C82305

or C82306

serial interface card
To use the C82305✽ or C82306✽ serial 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, see the C82305✽ or
C82306✽ interface card manual.

Selecting a baud rate

You can select from the following baud rates: 300, 600, 1200, 2400,
4800, 9600, and 19200 bps (bits per second). To set the baud rate,
see the bit-rate selection table in the C82305✽ or C82306✽ 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 r eceive 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.
