B&B Electronics 232MSS2 manual Default Values, Help Screen Un-Install, Selecting Ports

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> <ABCDN> 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:

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><ABCDN>

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:
