Hi,
I'm writing a cashregister program that needs to send data to a card terminal to make payments.
On the computer runs a program that handles communication with the terminal. This program is listening through TCP port 12555. Al the programs run on one computer.

So i need to send data to TCP port 12555 and wait for the answer.
ex.:
TR 3900 = TR is commando, 3900 = 39.00€

answer:
200 = transaction OK
400 = transaction refused
....

any suggestions ?
thnx
