Verifone ux100 Manual
Communicating with Serial Port “Verifone VX520”
I’m sending data through serial port to “Verifone VX520” payment device.
It is my first trial to communicate with such devices
SerialObj.Open; string input =
"02hPUR.10.99._04.634._010010FFFFF.0808.123456.
.03h"; byte asciiBytes = Encoding.ASCII.GetBytes(input);
SerialObj.Write(asciiBytes, 0, asciiBytes.Length);
As per the structure this message should send some amount and appear it on the machine but what I got is only this message “Sending Ack” And when I tried to read acknowledgment I got only this character
