27 MODULAR SMAR T SWITCH 6.3 Command-Line Options The control software supports a number of command line options that allow the utility to be installed and run in several different formats. They also allow a number of default settings to be changed and different hotkey combinations to be selected. Options are specified after a forward slash on the [...]

29 MODULAR SMAR T SWITCH To use HOTKEY within Windows, you must first install the control software in your computer’s memory. Do this before you run Windows, because once you are within Windows, resident programs cannot be loaded. You can then activate HOTKEY by clicking on HOTKEY.COM, HOTKEY.PIF, or an icon associated with these files. The contr[...]

43 MODULAR SMAR T SWITCH 8.4 General Hints and Tips 1. Always use the control software when using file-transfer software: Many packages such as Laplink Pro will not operate without the control software installed. 2. File transfer requires a protocol of 8 bits per character, 1 stop bit, no parity, and hardware handshaking. When using RS-232 with har[...]
