Epson LQ-2070 The C82305, and C82306, serial interface cards

The C82305
✽
and C82306
✽
serial interface cards
To use the C82305✽ or C82306✽ serial inter fac e card, see the
sections below for information on the correct baud rate, handshake
timing, and error handling. For all other data transfer conventions,
such as word structure and communica tions 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 ra te,
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 tha t it cannot receive data. W h en 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 asterik (✽).
The printer ignores all other errors, including framing and overrun
errors.
