Using a serial interface card (C82305
]
or C82306
]
)
To use a serial interface card (C82305
]
or C82306
]
), 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 your
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 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.
