DHES

I am able to control my credit card terminal from the computer. What I'd really like is of course to automatically send the amount directly from POS as a credit/ debit card sale is being rung up. This could simply be a disk file like the pole.dat file containing the total amount (I was hoping that pole.dat actually indicated the type of payment so I could just use that, but it turns out it doesn't). I would then monitor this file for changes from my own program and pass the amount on to the credit card terminal. Alternatively, I was thinking of monitoring the journal file or the temporary print file (but then I'd have to print an invoice for every credit card purchase). Anyway, it would be a lot simpler with a file containing only the amount to pay (and possible payout amount for debit cards).
