Re: [ptxdist] Backspace not working in terminal (using ssh)

[Roland Hieber <rhi@pengutronix.de>]

Hi Wolfram,

there are historically different handlings of backspace, one is
Ctrl-H, as mentioned by you below. The exact setting depends on the
terminal emulator (some terminal emulators can also switch the
behaviour, e.g. in putty, look under Terminal -> Keyboard). If backspace
works for you without the stty line, then there is no harm in leaving it
out, but the backspace behaviour could be different when connecting to
the board with a different terminal emulator.

For reference, when I type `stty -a` on my xterm, it says :

    erase = ^?;
