XWB has a few rough spots:
1) Apply the hotfix to BREAD^XWBRW that detects if a network error occurs. The unmodified code only works well under Cache, which seems to set $T=0 on error (which is not standard).
2) While at it, clean adjacent code as well. The timeout value supplied is not actually used as the number of second. It works out that the timeout value will be twice what is supplied.
3) CONNTYPE^XWBTCPM uses a hard-coded timeout of 5. Could this be made a system parameter?
4) On a new log-in, a local variable is set to "XUS SIGNON", but the context is never actually set. If there is junk in ^TMP from a previous connection it will interfere and prevent XUS SIGNON SETUP from running.
5) Should setting the context to "" clear ^TMP? Seems like it should.
To the points above:
1) Done.
2) It's messy but works, so I'm going to leave it. The code does cut the timout value by half, so the wait time is right after all.
3) I looked at this wrong. It's OK as it stands.
4) Done.
5) Done.
