-- This file defines the mib struct of RS232 Port in SN0116a(sn3101). Noted by YangLv, Aten, 20050413
-- We delete some mibs which are not useful in SN0116a. The deleted mainly are related with SYNC table
-- We attach this mib node on enterprises.aten.sn0116a subtree
-- Because in sn0116a, we don't allow 'set' function in snmp package, YangLv changes all read-write
-- attribute to read-only
