MuxLite Example
The following provides a usage example for the MuxLite feature. It assumes that the module data port is connected to COM1
and the module diagnostic port is connected to COM2. Though individual AT commands are shown in this example, HDLC
packet encoding/decoding must be performed on all diagnostic port (COM2) commands and responses as described in the
MuxLite application note [13].
