[wxsig] T238 Lightning Damage

There was a lightning near miss (I think it hit a AM
broadcast station .1 mile away) that took out my
station.  The T238 LCD was blank but the LED was flashing.
There was no output to the TNC.  I found the MAX232
chip bad and replaced it.  Everything came up OK but
the barometer is erratic.  I suspect there was a
transient in the power that may have damaged a regulator
on the barometer board but haven't gotten into that yet.
Anyway, the T238 mostly survived and the sensors seem to
be OK as well except for the barometer.
