Serial Port Command Interface

The Cricket listener provides data in ASCII format to software running on the attached host over an RS232 interface. The serial command interface parameters are:

Transmission speed 115200 bits/second
Data format 8 bits, no parity
Flow control Xon/Xoff (``software'')
Stop bits 1

The ASCII-based serial port command interface is similar to the ``AT'' command interface that modems use. The command interface is accessible using standard utilities like HyperTerminal or minicom. Section 1.2 describes how to use these utilities to send commands to Cricket.
