SUMMARY
Programs that require user input should not be executed through the
extended stored procedure xp_cmdshell. xp_cmdshell does not support running MS-DOS programs that require user input.
MORE INFORMATION
There is no way to get the user input from any DB-Library (DB-Lib) client
utility to the server. xp_cmdshell was designed to suppress the console window on the server and not allow user input. It will run internal MS-DOS commands and 32-bit programs that require user input and return back to the client utility, but there is no way to provide user input back to the program. Running external MS-DOS commands that require this input will
cause the DB-Library client to wait indefinitely for this input and never
return control to the client. The SQL Server process will remain active and
cannot be terminated using the Kill command.
xp_cmdshell was not designed to allow user input to programs. To achieve this functionality, a new extended stored procedure can be written.
