- Help on Shelling
-
- The 'Shell' command is a very powerful but also very dangerous
- command. It allows the caller to run a DOS shell on the sys-
- tem, except that the caller receives the output, and the
- caller enters the keystrokes. The caller has complete control
- of the HOST system at the DOS level. Shell is a password
- and level protected feature of HOST2. The caller sees program
- output only if the programs use standard DOS output. Programs
- that write directly to the video screen will work, but will not
- be seen by the remote caller. As well, programs that use non-DOS
- methods of getting keystrokes will not receive the caller's
- keystrokes. Finally, under some systems, if the caller presses
- Backspace at the DOS prompt when the current line is empty,
- DOS will hang on the Host machine. As these are functions of
- DOS, there is nothing that can be done about these limits.
