[wxsig] Whither DS1994L?

[William Beals]

Bill:

If you can get to the T238 archives, I posted the test code on Saturday Aug
14th.  It turns out (that for good reason), posts with decent sized
attachments get filtered and require manual intervention.  If you can get
that post, great, if not, let me know and I'll send it to you directly.

Will,

 	Apologies, just catching up myself.  Yes, I can give this a shot. 
I have a second T238 I can try this on, now I just need to find the 
button-rj-45 adapter and I'm ready.
