3B1 with two voice lines?

[Steve Wampler]

I have two lines coming into the 3B1.  They are both configured
as voice lines.  Now, is there a way to switch the handset between
the two lines without having to hang one up?  When I'm talking on
one and a call comes in on the other, I'd like to be able to put
the first call 'on hold' and answer the second.  However, phtoggle
forces me to hang up the first call!  (boo).

Since I just got 3.51, I don't know if anyone has some phone
utilities for doing this.

While I'm at it, I (very) occasionally want to use one or the
other as a data line.  Is there an easy way to do that?  Note
that I'd like to be able to select *either* line as the data
line -and- I don't consider going to the phone manager windows
a really suitable approach - I want a command I can enter!

Thanks for any help.
