Communicate with keypad device on comm port 1

[JimDenton]

I am trying to modify a Clipper Point of Sale application written using the Summer '87 version. The requirement is to add a pin-pad (connected via comm port)to enter a debit card security code. Does anyone know how to communicate with such devices over a comm port?

TIA

If the reader simply stuffs characters into the com port then you need some sort of coms lib. I use Clipper Tools but I think that there are some free ones on Oasis. This should then be only a couple of lines of added code.

Reply if you need more help.

I agree with Bozz. Just treat the key pad as any other serial device sending information to the serial port. For Summer '87 I prefer to use SilverComm as third party library to handle the communications.
