From an old FP DOS app I did, I used the following to pop the cash drawer open:

!echo chr(255) > &ComPort

I have a table that holds configuration information for each workstation on the network which includes what port the cash drawer is connected to. I define the variable ComPort to hold such port information -- e.g., COM1, COM2, LPT1, LPT2.

I am sure you could also use FOPEN(), FWRITE(), and FCLOSE() to do the same thing I did.
