COMMAND

Change SW1: Software dip switch #1. The dip switches are the only commands
that do not use the ^A parameters. Instead, they use a ^AB sequence followed by
an 8 digit 0 or 1 code.

For example: ^AB10101011^D215 will configure the printer for a text equivalent
enquiry response, accept control codes, even parity, disable parity, disable echo,
8 data bits and enable XON/XOFF flow control.

Enquiry Response: This determines what the printer will send back in response
to an enquiry. See chapter 5.

Control Codes: This switch setting will allow or disallow printer response to control
codes (below 20h). Special Note: When using parallel communications, this switch
will be automatically set to 0 and control codes can only be disabled by JP1 on the
parallel board.

Parity: Selects either even or odd parity error checking.

5

Enable Parity: Enables or disables parity error checking.

6

Echo: If this feature is enabled, the printer will echo all received characters to the
serial port.

7

Data Bits: Choose 7 or 8 bit data.

8

XON/XOFF: Enable or disable XON/XOFF software handshaking. CTS/RTS
hardware handshaking is always enabled.
