Subject: Generic Protocol Error --> Error opening serial device "COM27" The
system cannot find the file specified.
To: <[email protected]>
Hi Curt
I have been trying for a few weeks now to get FG to transmit data to a
serial port COM27 via the generic protocol, and for some reason unknown to
me the simulator simply will not comply. I have several other programs
which use this port with out a problem, I am using a usb to serial cable
"GigaWare" I'm not sure what exactly is going on but I really could use
some developer insight on this one. I had planned to use FG as a the
simulation platform for my autopilot design. I have the hardware and
software already to go, just need to get FG talking to the serial port.
