Serial Port Setup

Description Use this command to establish the serial port communication parameters. After
receiving this command, the printer will automatically reset, enabling the new rate.
To send commands and data to the printer, the host’s serial port parameters must match the
printer’s serial port parameters. Verify the printer’s configuration settings with the
AutoSense/Dump Mode Printout, see the printer’s user manual for details. The printer’s
default serial port parameters are:
9600 baud,No Parity, 8 Data Bits, 1 Stop Bit
Change the printer’s serial port parameters with the Y command after communication has been
established with the host. The host parameters must then be changed to resume
communication.
