User`s manual

This sets the data transfer rate at 9600 Baud with no parity check. It specifies 7 data bits and 1
stop bit. If you later change the printer's data transfer rate, parity check, data bits, or stop
bits be sure to type a new Mode command to change the parameters on your MS-DOS computer.
(See your MS-DOS manual for a full description of the Mode command.)
If your printer is connected to the COM2 port, substitute COM2: for COM1:.
Note: If you plan to use your printer often to print documents from your MS-DOS computer,
include the two Mode commands in your AUTOEXEC.BAT file, the program that runs every time
you start up your MS-DOS computer. This sets the printing parameters automatically each time
you start up. (For more information about the AUTOEXEC capability, see the owner's guide for
your computer or operating system.)

Matching handshakes
Whenever you use a serial connection to send information from one device, such as your
MS-DOS computer, to another, such as the LaserWriter II, both devices must be set to
recognize the same handshake. The handshake tells the computer how to know when to start
sending information to the printer.
___________________________________________________________
Important-If the handshake settings on your computer and printer are different, portions of
your document may not be printed, particularly if it is a long document.
___________________________________________________________
Your MS-DOS computer normally uses a handshake known as DSR/DTR (also known as DSR or
DTR ), but your MS-DOS application program may automatically change the handshake or allow
you to reset it.
Note: If you're using DSR/DTR but aren't using a standard cable, make sure that the cable
connects pins 6 (DSR) and 20 (DTR) on the RS-232 port of the LaserWriter II to their
counterparts on the serial port of the MS-DOS computer.
The LaserWriter IInt is preset with the XON/XOFF handshake, so if your MS-DOS application
program permits, select the XON/XOFF handshake.
If your MS-DOS application program requires the DSR/DTR handshake, you need to change the
handshake on the LaserWriter IInt to DSR/DTR by sending the following PostScript program
from your MS-DOS computer to the printer.
Note: To set the handshake for use with the Diablo emulation mode, described later in this
appendix, substitute the characters interactive for batch in the two words where batch appears.
This program retains the default printing parameters of the LaserWriter II, other than the
handshake. You matched those settings on your MS-DOS computer earlier when you typed the
Mode commands. To reset the other parameters, change to the ETX/ACK handshake, or check the
handshake.
The LaserWriter IIntx handshake
The handshake on the LaserWriter IIntx is determined by switches 5 and 6 on the left side of the
printer. To set the DSR/DTR handshake, place switch 5 in the up position and switch 6 in the
