The sfo-connection-state element in an ic-get-error-stats is documented in the 1.15 API (haven't looked at others) as:
|Connection state with peer. Possible value: "not connected", "waiting for connected", "waiting for not connected", "connected", "waiting for teardown", "unknown"|
...which is correct on older models, for example a healthy 3170A running 8.0.2P5D6 reports:
However, on 3270's (8.0.1P5) and 62x0's (running 8.1D4) invented a new value, "Established":
While this is easy enough to accommodate for (despite the inconsistent use of capitalization relative to the rest of the API), the bigger concern is what other states should I expect? Is there an open BURT to attach a case to?
