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

256bytes, 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.
