ETX/ACK 4375171 203
Note: Because the LaserWriter IInt component that registers the options can wear out with
excessive use (several thousand changes), change the options only when necessary. The first
two lines in the PostScript program for resetting the LaserWriter IInt help protect that
component by stopping the process if the Options number is already set the way you want it.

Parameters for the LaserWriter IIntx
Your LaserWriter IIntx is preset to receive information with no parity check, 7 data bits, and
1 stop bit. If switch 2 is in the down position, the data transfer rate is 9600 Baud. If it's up,
the rate is 1200 Baud, unless you have disabled the 25-pin port by placing switches 1 and 2 in
the up position.
To set the XON/XOFF handshake, place both switches 5 and 6 in the up position. For DSR/DTR,
place switch 5 in the up position and switch 6 in the down position. For ETX/ACK, set switch 5
down and switch 6 up.
Note: If you change any switch setting while your LaserWriter IIntx is printing, the printer
stops printing immediately.
You can change any of those settings by sending the following PostScript program to the
LaserWriter IIntx:
serverdict begin 0 exitserver
statusdict begin 25 BAUD OPTIONS setsccbatch
Instead of typing BAUD when entering the program, type the data transfer rate, which can be
300, 600, 1200, 2400, 3600, 4800, 9600, 19200, 38400, or 57600.
Use Table C-1 to determine the Options number. Type that number where OPTIONS appears in
the program.
Note: The LaserWriter IIntx component that registers the options, unlike its counterpart on the
LaserWriter IInt, does not wear out with excessive use, so you can change the settings as often
as you like.

Sending the program
To send the PostScript program, follow these steps:
1. Use any text editor to type, check, and if necessary correct the program.
If you don't have a word-processing application program, you can use EDLIN, a simple text
editor built into the MS-DOS operating system and described in your MS-DOS manual.
2. Instruct the computer to print the file that contains the program.
If you created an EDLIN file, use the MS-DOS Print command. Instead of printing, the
LaserWriter II resets its parameters. The changes take effect at the end of the current job, and
they remain in effect until you change them again, even if you restart your printer.
