Unlike many places inside the IOC, there is no built-in length limitation to 
the value that can be placed in a link field using dbLoadRecords(), which 
means that the @parm part of a hardware link address can be as long as you 
like.

Of course if you want to read or update the field through CA there is a 40 
character limit to the string you can pass as a DBR_STRING, and with the new 
array-of-chars support in 3.14.11 using the @ field modifier I believe CA will 
still limit you to passing at most 72 characters to/from a link field.

HTH,
