Using A Serial Interface Card (C82305 Or 82306 ); Selecting A Baud Rate; Handshake Timing; Error Handling - Epson FX-880 User Manual

Using a Serial Interface Card (C82305 or 82306 )

To use a serial interface card (C82305 or C82306 ), see the
sections below regarding 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,
1800, 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 asterisk ( ).
The printer ignores all other errors, including framing and
overrun errors.
