;* Abstract:
;*
;* This finite state machine defines ISO-HDLC ABM protocol, plus
;* 2 (REJ), 10 (modulo 128).
;* This same finite state machine has been defined in IBM
;* "Token-Ring Network: Architecture Reference".
;* The main differences from the IBM specification:
;* - XID and TEST handling have been removed, because it does
;* delong to IEEE 802.2 standard and DLC API support XID and TEST
;* frames only in the SAP level.
;* - The indications sent to the higher level have been specified
;* according to the IBM LAN Techical Refernce and IEEE 802.2
;* standard.
;*
;* THIS DEFINITION FILE IS COMPILED BY FSMX COMPILER TO C CODE!!!!

;* Revision History:
;* 26-MAY-1991 by o-anttis
;* - All XID and TEST stuff have been removed
;* - All IH (Inform Higher level) primitives have been changed
