SNMP GetNext for MAC address

I have many different versions of an SNMP tool that can getNext values.

My problem is on MAC addresses. Below is an example of the MAC address result. It parses fine but the translation .... not sure how to get it to get it to work. And, I need to use ASL not perl for this.

apMAC-->\X-00-\X-16-

If I do a hexToString the result is still -->

The code segment I am using to getNext is below with the hexToString in there.

      result = tm->snmpActGetNext(snmp, agent, oid)?IGNORE;

      result = tm->snmpActGetNext(agent, oid, snmpTimeout, snmpRetry, snmpPolicy, snmpFormat)?IGNORE;

      curOID = result[0];

      tempVal = string(getOID[0]);

      if (tempVal == "MacAddrTable")

            {

              getResult = hexToString(result[2]);

              FIX_MAC(getResult);

            }

FIX_MAC(getResult) {

   input=getResult;

    MAC:{
