    Hello,

    can someone explain me what's the use of the WRT54G RS232 Mod ?

    Is it possible to get Link Quality Stat over RS232 ?
    Are there commands i can send to the WRT54G over RS232 ?


    with kind regards
    Steffen

    You don't say which version but I assume WRT54GL or older inux devices

    The most use is that it gives you a serial console session - will show boot messages/ may allow interaction with the bootloader. When router running it should give a Linux Busybox command line (similar to Telnet) and you can use any Linux commands that are built-in. Particularly useful if you are experimenting with routing/ dhcp etc and you may block access by Ethernet. A more advance use is to hook up a dial-up modem for fallback or remote dial in access.

    yes you're right. I have a WRT54G and 2 WAP54G. My idea was to use the RS232 Port to built in an rs232 Bluetooth module and send informations to an ATMEGA32 µC - 4x20 LCD Display.

    Is there a overview about commands i can send over RS232 to get connection stats like pings, signal strength, mbit/s ?

    regards
    Steffen
