VISTA INSTALLATION AND OPERATION MANUAL
11
Maximum computers command
This command tells the Vista system the total number of computers connected. It is used so that
computer scanning can bypass unused ports on the unit. For example with an eight-port unit if no
computers were connected to ports 7 and 8 you could scan computers 1-6
and bypass 7 and 8.
To
issue the command press and release the
left
Control Key, type
"P"
,
enter the total number of
computers, and press
<Enter>.
Follow with the Keep command to save the new setting in the unit's
non-volatile memory.
PS/2 to serial mouse translation, wheel mouse
You can use some computers with PS/2 mouse interfaces and some computers with serial
interfaces. You must issue this command on each computer, which is serial. You must switch to
each computer and issue the command.
To configure a computer for a serial mouse, press and release the
left
Control Key, type
"Q1"
, and
press
<Enter>.
Follow with the Keep command to save the new setting in the unit's non-volatile
memory. To restore a computer which was previously set to serial to regular PS/2 use Q0 instead of
Q1.
Whether a computer uses a PS/2 wheel mouse or a regular PS/2 mouse is learned by Vista when
the computer loads its mouse driver. This will override any previous setting. You can tell Vista to
change its PS/2 communication to regular or wheel with the Q command. You can also save it to
non-volatile memory.
To configure a computer for a wheel mouse, press and release the
left
Control Key, type
"Q2"
,
and
press
<Enter>.
Follow with the Keep command to save the new setting in the unit's non-volatile
memory. To restore a computer which was previously set to wheel mouse to regular PS/2 use Q0
instead of Q2.
Null command
This command is used to re-synchronize an out-of-sync PS/2 mouse. Such a condition can result
due to transients, spurious power-up effects, or plugging and unplugging of cables with live
equipment. The command may need to be entered once or twice, depending if the mouse is out-of-
sync by one or two bytes. Microsoft mouse driver version 9.01 or later corrects this inadequacy of
previous drivers and renders this command unnecessary. To issue the command, press and release
the
left
Control Key, then type
"N"
