Since mask order is important: Specifying asterisks on the  first 

mask compared to specifying hyphens on the first mask is  rel-

evant (this is from Special Characters and Blanks inside How

Virtual Terminal Masks Are Used on the TPX  documentation: 

-


You can use two special characters in masks.

 

An asterisk (*) in the mask indicates that the product should 

substitute the character from the physical terminal ID   at the 

same location as the asterisk  before making a  comparison.

 

A hyphen (-) in the mask indicates that any character in that 

position will match.

 

Blanks are significant. If a blank appears at the end of a phy-

sical terminal mask, the last character of the physical  termi-

nal ID also must be a blank.
