EIA–232D Serial Interface Protocol
You can select the following serial interface protocol parameters from the
control panel to meet host interface requirements:
X–ON/X–OFF – The printer transmits an X–ON character (hex 11) when it
goes on–line or when the buffer is almost empty. The printer transmits an
X–OFF character (hex 13) when it goes off–line or when the buffer is almost
full.
EIA–232D Serial Interface Configuration
Verify or change the following serial interface options at the control panel to
meet your application requirements. (Refer to Chapter 4, Printer
Configuration.)
• Data Rate (Baud rate selected from the control panel)
• Data Word Length (7 or 8 bits)
• Stop Bits (1 or 2 bits)
• Parity (none, odd, even, mark, or sense)
• Data Terminal Ready response logic (true, false, on–line buffer not
full, off–line buffer full)
• Request to Send response logic (true, false, on–line and buffer not
full, off–line or buffer full)
• Reverse Channel response logic (true, false, on–line buffer not full,
off–line buffer full)
