[comp.protocols.iso.dev-environ] unexpected token indication

Hi,

I'm porting ISODE 6.0 to the TLI transport interface. I've had some success
but I'm baffled by the present situation!

So far I can initiate an ftam session on the remote machine and get the 
message 'connected' and a prompt e.g.  'remote-machine>'

Any local command executes OK.
Remote commands (e.g. get file, put file etc) produce this response:
	TWrite called, with 2 bytes of data (0x1 and 0x0) followed by
	TWrite called, with 2 bytes of data (0x1 and 0x0) followed by
	TWrite with about 50 bytes of data (dependant on command)

The responder starts to abort the connection when it receives the 1st 2 bytes. 
It sends some data containing the string "unexpected token indication (0x0)"
to the initiator which in turn aborts the connection!.

The main error message is as follows:
	FTAM protocol error (unspecific): unexpected token indication (0x0)


Do you have any ideas as to what may be the problem?
Is it a configuration or a coding error?
Is it in some way a transport error?
Where can I expect to find the solution? Any tips/ideas?
The TLI must be working reasonably well to get a connection and session.
I would expect each pdu to be at least 20 bytes long! (not 2 bytes)


Thanks in advance
