Depending how many wires your lead has determines what kind of handshaking to select.
Although you can have a hardware lead and still use software handshaking.
Not sure what OS you have, but for Windows 7 you have to:-
Click Start then Control Panel
Start Device Manager
Open Ports (COM & LPT)
Double click the port you plugged it into (COM1)???
Select the Port Settings tab
and edit the page:-
Bits per second 9600
Data bits 8
Parity None
Stop bits 1
Flow control None
Just a minute! now that you've done that, I seem to remember the default Baud rate is NOT 9600.
On my KAM it's 2400 and you have to press * on the keyboard's numpad to start it up.
You'll have to go through the manual and double check the default values for the serial port.
If it is indeed a very old machine, it might be worth resetting it by taking out the battery.
I can't even remember if the PK232 had battery backed RAM or not...
Anyway, in short, you have to set the computer to the PK232's serial settings before you can change anything.
