The following TCL command from a client's system 'looking at' another d3/win system should give you the clues you need:
COUNT fsi:[//192.168.60.121]dm,fhb,p
Thus you could build a super-q-pointer to simplify the syntax:
SOMESUPERQPOINTER
001 Q
002
003 fsi:[//resolvable_d3_server_name]d3accountname,d3filename,
For example, where 'yourotherd3server' resolves to an IP address via your hosts file [or just use the IP address] where a d3 account called 'myd3account' exists containing a file called 'myd3file':
remotemyd3file
001 Q
002
003 fsi:[//yourotherd3server]myd3account,myd3file,
Note the placement of commas, they are important.
