I have a 4 serial port keyspan usb-serial adapter and Astro IIDC

I have my GPS on serial port #1, my autostar on port #2 and use the
2 other port for micro controller communications
Actually no, it shouldn't select a port if it's marked for exclusive
use. When Astro IIDC tries to acquire a posix serial port, it scans
through all the available serial ports, then tries to open exclusive
access to each one. If another driver is using it, then the exclusive
use call should fail and it continue searching for a port. However if
the port isn't in use when we check, then it's assumed to be open and
the one your connected too.
Yesterday I was using port #1 with minicom abd when I started Astro
IIDC It took the same port..
So may be minicom doesn't open the port in exclusive mode .
We will look into adding this feature in the 3.0 release of Astro
IIDC.
Ok.
So In the mean time I'll reorganize my serial port usage.
Thanks,
Rodolphe
PS : If your code is in C/C++ using carbon I have a class ready to
use for serial port selection, the one I use in AutoStarX
