Use Of “?” Wildcard Symbol - Motorola MICOM-2ES Owner's Manual

•
A receiving station will accept a wildcard character as a substitute for the
alphanumeric character in its own address that occupies the same position. This
means that the wildcard character is a substitute for any of 36 characters and
digits (A to Z, 0 to 9) in the Basic 38 character subset.
•
Multiple wildcard characters can be used in different positions of the same
address (basic or extended).
See Table 2 for examples of patterns using the "?" wildcard symbol.
