LaserWriter Pro 630: PostScript Commands to Change Baud Rate

Here are the PostScript commands to change the baud rate on the serial 9-pin port.

Note: The LaserWriter Pro has four user-configurable communications settings; these are thumbwheel switch positions 6 through 9. Page 126 in the LaserWriter Pro User's Guide outlines all of the default settings for these positions.

To change the baud rate to 9600 for switch position 6 on the serial 9-pin port:

%%Begin

(%SerialB_NV%) <</Baud 9600>> setdevparams

%%End

The possible baud rate values are: 300, 600, 1200, 1800, 2400, 3600, 4800, 7200, 9600, 19200, 57600.

The integer after "SerialB_NV" correlates to the thumbwheel switch setting. For example:

%SerialB_NV% - changes settings to thumbwheel switch setting 6
%SerialB_NV2% - changes settings to thumbwheel switch setting 7
%SerialB_NV3% - changes settings to thumbwheel switch setting 8
%SerialB_NV4% - changes settings to thumbwheel switch setting 9
