	When I dial out from the trailblazer to a 2400 baud modem
	I hear the 1200 baud carrier, then the 2400 baud carrier,
	and then the hissing sound....
	Many times the trailblazer will produce a "hooting" sound
	out the speaker and trash the connection.
	Has anyone had these symptoms?
Yes, occasionally. And not only when calling other
brands of modems, but even when calling a TB+ (rev.
3.0 or 4.0) with the calling TB's S50=3. In my case
S95=2 (on both calling and called TB's), haven't
tried it with S95=0 yet. But the described problem
also occurs when calling a 2400 modem that doesn't
have MNP.
