4.3.6.B Mouse Interfaces
IBM PC type computers have several types of mouse interfaces as well. The
ServManager supports four: PS/2, Microsoft serial, PC Mouse (Mouse
Systems), and 8-bit serial.
The PS/2 mouse interface uses a 6-pin mini-DIN connector and is similar to
the PS/2 keyboard interface. The advantage of the PS/2 mouse is that it is
built onto the motherboard and doesn’t occupy any of the CPU’s serial ports.
The serial mouse interfaces all use the EIA/TIA RS-232 serial standard,
implemented on either a DB25 or a DE9 (“DB9”) connector, and all of them
communicate with the PC at a data rate of 1200 bps. Microsoft mice use a
3-byte/7-bit protocol; unlike the other three types of mice you can choose
from, they do not support a third button. 8-bit serial mice use a 3-byte/8-bit
protocol. PC Mouse (also known as Mouse Systems) serial mice use a 5-byte/
8-bit protocol; many lower-cost mice have a switch that you can set for either
Microsoft compatible operation or PC Mouse compatible operation.
4.3.6.C Command Procedure
Selecting the Apple or Sun keyboard/mouse combo only requires a single
command; selecting an IBM type keyboard and mouse requires two
commands—one for the keyboard and one for the mouse. When you issue a
command to change from an Apple or Sun keyboard to an IBM type
keyboard, the ServManager will automatically set the mouse interface to PS/2;
until you make this keyboard change, any attempt to change from an Apple
or Sun mouse to an IBM type mouse will be ignored.
To set the keyboard mode or mouse interface of the currently selected port
on a single or master unit, take these steps:
• Press and release the left Control Key, then type [M];
• Referring to Table 4-5 on the next page, press the numeral key
corresponding to the code of the keyboard or mouse type you want; and
• Press
[ENTER]
.
For example, to choose the Sun keyboard and mouse, you would type
[CTRL] [M] [4] [ENTER]
. To choose a Mode 2 keyboard with a Microsoft
serial mouse, you would type
[CTRL] [M] [2] [ENTER]
followed by
[CTRL]
[M] [7] [ENTER]
.
