Using The Serial Interface Card (C82305 /C82306 ) - Epson Stylus COLOR 800 User Manual

Using the serial interface card (C82305 /C82306 )

When using a serial interface card (C82305 /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 the C82305 /C82306
interface card manual.
Selecting the baud rate
You can select the following baud rates: 600, 1200, 2400, 4800,
9600, and 19200 bps (bits per second). To set the baud rate, see
the bit-rate selection table in the C82305 /C82306 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 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.
