Part Number: SIM300
Function: GSM Module, Hardware Specification
Flow control is very important for correct communication between the GSM engine and DTE. For in the case such as 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. There are basically two approaches to achieve data flow control: software flow control and hardware flow control. SIM300 support both two kinds of flow control. In Multiplex mode, it is recommended to use the hardware flow control.
