65SCN7B.EXE

65SCN7B.EXE is a DOS TSR driver for the external serial

scanners. 65SCN7B must be loaded for any scanning to oc-

cur.
65SCN7B is generally installed in the AUTOEXEC.BAT

file, according to the following format:

65SCN7B [-option[value]] ...

65SCN7B uses command line switches to enable the desired

functions.

EXAMPLE:

65SCN7B -W

The descriptions of the command line switches, for

65SCN7B, are as follows:

Table 4-1

65SCN7B Options

Switches

Description

--? or --H

Either of these options results in a help screen that briefly describes

the various options.

--B[n]

Beep on good scan. Range of valid values for n:

0 = no beep

1 = beep (default)

--W

Enable the wedge mode of operation. Scanner data is sent to the

keyboard, using the method selected by the --P switch.
The absence of --W requires an application to request scanner data

through the API scanning method.

--O[n]

Time between outputting data, where n=0--9 timer ticks (~55ms).

For example: if “n” = 5, then five additional timer ticks (or 5*55 =

275ms) are put between each character sent to the keyboard buffer.
