I recently posted a note detailing my experience with flow control
on the Amiga serial port.  I had to hotwire pin 5 on my plotter to
pin 18 on the Amiga in order for the CTS handshaking to work.

Last night I was working on the Amiga and not using the plotter
so I did not power it on.  Guess what!  The machine would not 
kickstart until I unplugged the cable going to the plotter.
Turn the plotter on or unplug the cable and everything works fine.

After the machine is up and running, you still need to power on the
plotter or unplug the cable or whatever you are running will lockup.
This is true even if the application does not use the serial port.
Again, if I power on the plotter or unplug the cable all returns to
normal.

Do any of you understand what is going on here?
