Set up a communication terminal

In Linux:

• Open a terminal and run minicom -o -s as root or as a user with the right permissions to access the device (e.g., /dev/ttyS0) to which the cricket is connected. By starting minicom with the -o and -s option you will see the configuration menu directly.

• Select Serial port setup and set the Serial Device to the port to which the Cricket is connected.

• Select Bps/Par/Bits to be 115200 8N1. Hardware and software flow control can both be disabled.

• Save these settings.

• To see what you are writing on the screen, turn the echo function ``on''.

• Now you are ready to send commands to the Cricket; see Section 1.2.2 to continue.

In Windows:

1. Start HyperTerminal: In Windows XP, you can do this as follows:
   From Start-$>$All Programs -$>$Accessories-$>$Communications select HyperTerminal.

2. HyperTerminal will prompt you for a New Connection name; type in any name you want (such as ``Cricket'') and press OK.

3. In the next dialog box, select the Connect using option and set it to the communication port to which the Cricket is attached. For a direct serial connection, this port is likely to be COM1, COM2, or COM3; for a USB-to-serial connection, this port is probably COM4. Press OK after choosing the right option.

4. You now have to configure the serial communication protocol parameters. In the Port Settings dialog box, set Bits per second to 115200, Data bits to 8, the Parity to None, the Stop bits to 1, the Flow control to Xon/Xoff. Press OK.

5. You can now send commands to the Cricket unit; see Section 1.2.2 to continue.
