In bash I have the following terminal settings: ... $ stty speed 38400 baud; line = 0; -brkint -imaxbel iutf8 ... and then in gdb using the shell command likewise: ... (gdb) shell stty speed 38400 baud; line = 0; -brkint -imaxbel iutf8 (gdb) ... and likewise using a shell session: ... (gdb) shell $ stty speed 38400 baud; line = 0; -brkint -imaxbel iutf8 $ ... But in TUI, we get different settings (removed runaway indentation for readability): ... (gdb) shell sttyspeed 38400 baud; line = 0; min = 1; time = 0; -brkint -icrnl -imaxbel iutf8 -onlcr -icanon -echo (gdb) ... and consequently the shell is not really usable. This is PR tui/18215. The easiest way to fix this is to just temporarily leave TUI while in the shell, leaving the output of the commands in CLI mode, but that's a bit confusing. Fix this (as suggested in the PR) by restoring the initial terminal settings while in the shell command, such that also in TUI we have: ... (gdb) shell sttyspeed 38400 baud; line = 0; -brkint -imaxbel iutf8 (gdb) ... Tested on x86_64-linux.
