  • Page 26: Flow Control

    MC55 AT Command Set 1.6 Flow Control obile Flow Control Flow control is essential to prevent loss of data or avoid errors when, in a data or fax call, the sending device is transferring data faster than the receiving side is ready to accept. When the receiving buffer reaches its capacity, the receiving device should be capable to cause the sending device to pause until it catches up.
  • Page 27: Unsolicited Result Code Presentation

    Hence, when the TE receives the echo of the first character "A" of the AT command just sent by itself it has control over both the receive and the transmit paths. This way no URC can be issued by the MC55 in between.
