I need to create a half duplex modem that can be address via a COM port. I have seen the FSK examples. I can use them to generate FSK out of my analog device. I cannot control the bit stream out of the MT Generate. I tried the user input, but it then it no longer runs continuously. I also have no clue how to attach the bit stream to the COM port. I want to see an 11 bit (1 start, 8 payload, 1 stop, 1 parity) word that is modulated in FSK as a start. If I could send hex from one putty terminal to another that would be ideal.
