Hi Rod,

Dunno if I posted these before, or if you're even interested, but these are
the updated on-line help screens from the Sportster's new V.34+ EPROM. 
It's rather surprising just how configurable the modem really is, although
I can't really see much use for the majority of features listed. 
Nevertheless, I guess it's still better to have them and not need them,
instead of the reverse.
