Does anyone out there have a list of the X.29 protocol ids which are
negotiated in the X.25 connecting packet?

I know about ITI (Interactive Terminal Interface) being 01000000
Thanx.

Get a copy of ISO TR 9577
	"Protocol identification in the network layer"

For X.25 the secondary protocol identifier (1st byte of call user data) is
used.  The table of assigned values is:

Octet	Protocol
hex
00	ISO 8473 (Inactive subset)
01	CCITT X.29
02	Reservied by CCITT T.70
03-3F	Reserved by ISO 8073/Add1
81	ISO 8473
82	ISO 9542
86	ISO 10030
83	ISO 8878 Annex A
FF	Extension

Per RFC 1060, note that as of January 1990, in ISO 9577 the ISO SC6/WG2 has
also approved the (previously de-facto) assignment of:

  CC	Internet IP		[as in IP, ICMP, TCP, UDP, etc.]
