Terminal Emulation is a built-in function on most operating systems (ex: HyperTerminal). Before using any terminal emulation program, any services using the COM ports must be stopped. For example, if you are running a serial version of APC's PowerChute software, the APC UPS service must be stopped prior to running the terminal program. APC’s smart serial ports put TxD on pin 1 and RxD on pin 2. This means you go nowhere if you use a normal straight through serial cable. In fact, you might even power down the load if you plug one of those cables in. This is due to the odd routing of pins - DTR and RTS from the PC usually wind up driving the on/off line.

You can also use an old DOS trick to send particularASCII values that may not have control-key equivalents. Hold down the Altkey and type the decimal ASCII value on the keyboard's numerickeypad (not the number keys along the top of the keyboard),then release Alt. Precede the number with a 0(zero). For example, to send ASCII 133, press and hold Alt, type 01 3 3 on the keypad, then release Alt.

Don't leave out the 0 (zero) preceding the number! Ifyou do, the actual value sent can be changed in odd ways. For example,ASCII 14 sent as Alt-down 1 4 Alt-upworks fine, but ASCII 15 sent as Alt-down 1 5Alt-up gets translated to ASCII 164.
