According to the wavecom Open AT Basic Development Guide (revision 011 dated May 2005; page 57), there cannot be simultaneous serial flows. My interpretation of this is: one cannot be subscribed to both UARTs for sending/receiving data.
However, after reading numerous posts here, this is clearly not the case. Is my documentations too old, or am I not understanding something?
I would like to keep using UART1 for AT commands, and UART2 for forwarding internal application’s TCP/IP data to a hyperterm that writes it to file.
Is this possible?
