How to Send Data while connected in Data call

Good Day,

I have two modems - one with OPEN AT app that initiate a data call to the other modem connected to a PC. I use the ff. code to connect via data call:


Call setup was successfull because both modems received “CONNECT: 9600” response.

My questions are:

  1. How to transfer data from my OPEN AT app to the other modem?
  2. How will my OPEN AT app receive the data transferred by the other modem?

Thanks in advance for the support.


Use FCM - the Flow Control Manager.
