A further note on System 7.0 and Z-Modem. I use Z-Term and under System 6.0.7,
My 5/105 IIsi, and my Practical Peripherals modem, I was able to achieve about
98% efficiency running MF 6.1b9. Now under System 7.0, I can only obtain about
94% efficiency. 

Because of this change I am led to believe that either A) Z-Term doesn't work
as efficiently under System 7.0, or B) something with Dave Alverson's Z-Modem
algorithm isn't getting along as well with the way the ports are handled under
System 7.0.

Any comments?
