Re: special characters -- LINUX5250

You are absolutely correct, thank you!  I have read some of this before,
and I even pressed attention and went into those options earlier today. 
I obviously didn't see *ESC, and for some reason I thought the mapping
went the other way.  I didn't see enough keys, so I wrote it off.  (BTW,
the &T didn't work for me.)

This may also explain why F5 didn't work when I dialed into the router
and telnetted to the AS/400 (which has ABSOLUTELY NOTHING to do with
tn5250).

The passthru is dialup which probably uses sna.  I just type "STRPASTHR
rmtlocname" and signon after it connects.
