   Hello Vince!

I dont have telnet installed - it is an alternative to BINKD. Binkd sessions 
are over 24554. fido:// ones are 60177 and the telnet:// ones are 60179. I 
think the later two are modem emulated IP connections(?) - IE: I needed EMSI 
to the old board, and it expires the "connector" to transmit some special 
chars to destingish between a mailer calling and human (wanting to go into the 
BBS)...

 VC> Let me know the results of your examinations as it might relate.

I'm guessing, that these were "dummy packets" from my old BBS - there was a 
zmodem option enabled to send a dummy zmodem transfer. Those dummy packets 
were zero bytes in size - and they stopped once I turned that option off...
