The Hot Key is a sequence of three keys that must be pressed
simultaneously to switch from one Smart Switch Port to another. For
example, the hot key sequence, <Left Shift> <ALT> <A|B|C|D|N>
states that the left shift, Alt, and either A, B, C, D, or N must be
pressed at the same time to select the corresponding Smart Switch
Port. N turns off all Smart Switch ports.
Default Values
If you type SSTSR on the command line with no parameters, or
omit any parameters, the default value of the missing parameter will
be used. The default values are:
Help Screen
If you are installing the SSTSR using the SSTSR.COM method,
you can type SSTSR ? and press the ENTER key to obtain a list of
the commands and their options.
Un-Install
The SSTSR may be un-installed easily by typing SSTSR - and
pressing the ENTER key. In some cases the SSTSR will not un-
install. This may be caused by another terminate and stay resident
(TSR) being installed after it. To un-install the SSTSR when this
occurs, the other TSR must first be un-installed, then the SSTSR
can be un-installed normally.
Selecting Ports
There are two different ways in which a Smart Switch port is
selected, either through the command line or by pressing the
predefined hot key sequence after the SSTSR was installed. When
a request to change ports is made, using either method, first the
current port is turned off, then the port selected is turned on. The two
methods are described as follows:
Description Default Value
Port Address 02F8h (COM 2)
Baud Rate 7 = 9600
Parity 0 = No Parity
Data Bits 8 = 8 Data Bits
Second Character 2 = STX (CTRL B)
Hot Key Sequence 1 = <Left Shift><ALT><A|B|C|D|N>
