snmp will not return a mac address

When doing an SNMP test, I am unable to get HM to return a mac address value either in the 'Reply' field, or when pressing the 'get current value' button (the returned 'value' field is blank).

An example snmp get that should return a mac address is:

1.3.6.1.2.1.2.2.1.6.x (where x is the value of an interface (NIC) on a server.

Problem - SNMP protocol does not have special data type to represent MAC addresses, it uses Octet String type. However MAC address stored not like any other text string...
I can change decoding method for this specific OID but its not universal solution

Ok. There is solution at www.ks-soft.net/download/hm447d.zip
Now if retrieved OCTET STRING contains some unprintable characters, HostMonitor displays sequences formatted %XX where XX is a hexadecimal code of a character (byte).
E.g. in case of MAC address" 00:40:69:2F:50:08" HostMonitor will show "%00%40%69%2F%50%08"
