Interface Cards
The C823051/C823061 serial interface card
To use the C823051/C823061 interface card, see the sections below
on selecting a baud rate, handshake timing, and error handling. For
all other data transfer conventions, such as word structure and
communications protocol, see the C823051/C823061 interface card
manual.
Selecting a baud rate
You can select from the following baud rates: 150, 300, 600, 1,200,
2,400, 4,800, 9,600,
and
19,200
bps (bits per second). When you set
the baud rate, see the bit-rate selection table in the
C823051/C823061
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 528 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.
