I'm getting nowhere with trying to get our 1186s to talk to a SUN running SUN
OS 3.4.  Does anyone recognise the following problems and know the solution?

I load all the appropriate TCP stuff under Koto; I've followed all the 
instructions re: TCP.CONFIG to the letter.  I then try to CHAT to 
the SUN Unix host, and in my TCPTRACE window I get:

11383/23: CLOSED ---> SYN.SENT
SEND: from 192.9.200.0:11383 to 192.9.200.1:23
11383/0 [SYN] window = 2000 checksum = 13058 length = 0
SEND: from 192.9.200.0:11383 to 192.9.200.1:23
11383/0 [SYN] window = 2000 checksum = 13058 length = 0
RECV: from 192.9.200.1:23 to 192.9.200.0: 11383
14700737/11384 [ACK,SYN] window = 4096 checksum = 58645 length = 0
11383/23: SYN.SENT ---> ESTABLISHED
SEND: from 192.9.200.0:11383 to 192.9.200.1:23
11384/14700738 [ACK] window = 2000 checksum = 52558 length = 0
Options:  maxseg:  536
RECV:  from 192.9.200.1:23 to 192.9.200.0: 11383
14700738/11384 [ACK,RST] window = 4096 checksum = 58642 length = 0
[TCP connection reset]
11383/23: ESTABLISHED ---> CLOSED

Then, after half a minute or so, I get a break window with the message

	Shouldn't happen!
	(HELP broken)

and the function that appears to have fallen over is TCP.OTHER.STREAM,
called by TCPCHAT.OPEN.

Am I missing something obvious or what?

Any help whatsoever very much appreciated .. this is driving me up the wall.
