Airmail2000: Developed
When using Winlink Express it can get hung if someone connects at the same time you are switching between  P2P & WL2K. Sometimes Winlink Express can  not reinitailizing the Kantronics KPC series and that is when Airmail comes to the rescue.

Having Airmail and Winlink Express setup witon you packet computer will become extremely import when the TNC is hung.

I have created a youtube video that shows what to do, Airmail & Winlink Express
(it opens in a new tab and to return close the tab)        
It only takes seconds to reinitailizing the hung TNC using Airmail that matches the Winlink Express comport setup.

Also I have other youtube videos on my @ve7ed Youtube channel.
