Odd probes at port 7777

[Ken Hardy <ken @ mailhost . bridge . com>]

Every couple of days we get an attempted connection to port 7777 from
scripps.edu, so I put a byte sucker on that port to log any received
data.  It seems to be a 4 digit and a 2 digit number separated by a
comma, followed by a carriage return.

Any idea what this might be?  No, it's not in the assigned numbers RFC
(rfc1700).
