Using A Serial Interface Card (C82305 Or C82306 ) - Epson LQ-670 User Manual

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 asterik ( ).
The printer ignores all other errors, including framing and overrun
errors.
