Rose electronic Vista Mini - Manual (Page 15)

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 mem-
ory.
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.
Keep command
The Keep command saves the current state of the Vista Mini’s custom settings.
These settings are scan enable, scan interval, each CPU’s mode and keyboard
LED state, maximum computers, the keyboard typematic value, and the mouse
translation for each CPU. These settings are saved in non-volatile memory and
become the power-up settings. To enter the command, press and release the
left Control Key, then type “K”.
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 com-
mand, press and release the left Control Key, then type “N”.
