I have been trying to learn about how to read Telocator Alphanumeric Protocol (TAP) messages being sent from a serial device. The system I would like to interface to is sending rs232 via TAP protocol. This information is typically sent to a paging transmitter, but I would like to read the data into my aduino. The TAP protcol needs to see the following series of events -
RED is what Arduino expects in TAP unit :
Green is what Arduino will send out in TAP units:
Listed below is a proper TAP sequence:
Would anyone have any advice on or sample code to do this initial sequence in arduino. How do you send a CR, ACK or ETX character?
