[plug] what uses port 98?

[BillK]

Hi,
	what uses port 98?  My listing shows it as something called "TACS". 
The last few weeks ipchains has suddenly started logging and denying a
few connection attempts on the port from different locations.  Last
night I got curious and probing showed a RedHat 6.2 box in Canada - with
most services showing so I presume no firewall! It seems likely its a
valid service of some kind, though why pick on my dialup connection?
