Dear all,

I am develop a button to connect RS232 and receive the message from it.

Do anyone know how know how to do this using VBA, ArcObject etc. ? I have search some material in the internet, they suggested to add "Microsoft Communication Contol" to the form and use "MSComm". However, my ArcMap (9.3) do not have "Microsoft Communication Contol".

Do anyone can help me ?
