Batch run Sun/solaris

[Deiter Scott]

We are very new to gnupg

we are running gpg to send data to one of our banks.
If the userid logs on and runs the script manually all is well.

However during the execution with in the job scheduler we receive this
error.

                gpg: cannot open `/dev/tty': No such device or address

So what parm or environment variable can we set to get past this error.
everything else is running rather well.
