Executing shell commands with the exec() function
I am trying to execute shell commands with the exec function, but the camera hangs.
When executing a shell command with exec(), like for example:
exec("fd:/shell.exe",2,"bd 19200"); (do not forget to type the absolute path)
the shell overwrites itself, that's why when the program finishes, the camera hangs. To prevent this, recall the shell at the end of the program:
exec("fd:/shell.exe",0,"");
