[Coco] DLOAD/HyperTerminal mystery

[Robert Gault]

Which version of HyperTerminal are you using? I have no problems setting it 
to 8-N-1 with version 6.3. I open HyperTerminal using a previously created 
connections entry labeled Null Modem. The properties are set or changed 
from the Menubar/Files/Properties/Connect_To/Configure. The connect_using 
is set for Direct to COM1.
