Using The Serial Port - Talk-a-Phone WEBS-PA-1 Configuration And Operation Manual

Using the Serial Port

5 Using the Serial Port
The Communications Module has a serial port which can be used to perform the following operations:
Execute Linux commands — for example, to change directory "cd", check memory usage "cat
1
/proc/meminfo", process statistics "ps".
2 View and edit the flash contents.
3 Configure mandatory parameters of the WEBS-PA-1.
To use the WEBS-PA-1 using a serial port:
1 Connect a null modem serial cable from the serial port on the Communications Module to an
available COM port on the PC.
2 Launch the preferred console/terminal application (e.g., HyperTerminal or TeraTerm) on the PC
and specify the following:
•
Baud rate: 115200 bps
•
Data bits: 8
•
Parity: None
•
Stop bits: 1
•
Flow control: None
3 Change the current working directory to /flash using the command cd /flash
4 Create or Edit the configuration file (configdbfile.txt) using the vi editor.
5 Run the configuration application to update the Communications Module configuration as follows
configApp <username> <password> <name of configuration file>
For example: configApp admin admin@123 configdbfile.txt
The configuration file requires a name=value pair separated by a new line. A "+" character is treated
as comment in the file.
An example of configuration file is shown in Appendix C: Sample Serial Configuration File
