Hi, carsey and Olivier:
let me describe the problem more detailly.
first, I use the the shell efi from the directory of
edk2\ShellBinPkg\UefiShell\Arm\Shell.efi
when i boot to the shell, the uart console print information like below:
Loading driver at 0x000BB914000 EntryPoint=0x000BB95A389 Shell.efi

Press ESC in 1 seconds to skip startup.nsh or any other key to continue.
problem starts here: if i press "ESC" ,it enter the shell correctly.but if i
press any key other than "ESC"
the console would not continue to execte(stop here),and "ctrl+c" do not work.
secondly, if i press "ESC" in the step above, i enter the shell, and if i input
the command that exist in the shell
(for example: help/ls),everything looks ok.but if enter the command that do not
exist in the shell,the console would not
response any more.for example,if i input a command like "abc", then press
"enter",the shell prints:
Shell> vol
Error. No current directory is specified.
Shell> ver

Shell> abc
at this step, i try to press "ctrl+c", but nothing happened.
i guess if there are some configs in dsc file to enable the ctrl+c feature. but
i am not sure.

The shell will create and event to monitor for CTRL+C if the platform supports
it. There is no requirement that the platform support it.

Hi,
Do you know if CTLR+C is supported by the shell? If no, do you know if your EFI
application support CTRL+C ?
Thanks,
Olivier
