  • s2e echo problem

    I'm facing with this problem:

    at work we have interfaced a BeagleBone Black (BBB) UART0 with a Lantronix XPort Pro (16 Mb) in order to make available the Linux console of BBB through
    network using 's2e' application.

    Ok, if I use a FTDI adapter (using TX, RX, GND signals) to connect on UART0 of BBB everything works fine (u-boot command line interface, Linux login console, shell).

    If I use the Lantronix Xport (using TX, RX, GND signals) to connect on UART0 of BBB a strange "echo effect" occours... it seems that every time I press "return" on keyboard the console receives this key two times and the Linux shell repeat the command I just typed in the next line;

    I'm using telnet to connect on s2e TCP port;

    this effect occours also in u-boot command line interface where there is nothing to configure (except 115200,8,n,1 serial parameter)

    Did you have a solution for this problem ?

    Let me know if you need more details about configuration...
