Change an Option 11c TID

This procedure is only intended as a temporary workaround to get a Meridian Mail system working in an emergency, ie: while waiting for new keycodes to arrive after some type of outage, etc.

When you use a temporary set of software (eg, does not belong to the site), the system will not data dump. The EDD data dump can only be done when this setting has been modified, either from within PDT or via a new set of ISM keycodes in LD 143.

This example is from a 2121 / 04.00T system, hence HEX offsets 9815 (Security ID) and 97bf (Aux ID) are used. Check the table below for other release HEX offsets. Notice how the Security and Aux ID's are split into transposed digit pairs, just to confuse you!
