This is the problem. You want to pass the raw hex to snmp_set_var_typed_value,
not an actual string. If cVal is an ASCII string, you need to convert it to 6
hex bytes before passing it in, and you don't want to be using strlen. In
other words, cVal should not be a printable string.

You are lost in a twisty maze of little standards, all different.
