The Backspace key in my SSH session produces strange characters instead of deleting characters.

In some cases, your proServer and the terminal emulator you're using on your local computer may have different interpretations of which control code the "Backspace" key should trigger.

You can view the proServer settings as follows:

$ stty
speed 9600 baud;
lflags: echoe echoke echoctl pendin
iflags: iutf8
oflags: -oxtabs
cflags: cs8 -parenb
erase  
 ^H

In this case, proServer expects the code ^H (Ctrl+H, ASCII 8). This is the default. In a Mac OS terminal, for example, this corresponds to the setting "Delete key sends Ctrl-H."

If you want to change the setting on the proServer side, you can add a corresponding command to your .bashrc file:

stty erase ^?

This would set the code to DEL, ASCII 127, which is another common setting.
