Hello everybody


I'm new to this group and I'm planing on using Astro IIDC mostly for auto-guiding using an

autostar on a LXD-55 mount with a 8" SN as the mains scope and an orion ST90 as the guide scope.


Is there a way to select a different port than the first posix serial port found by Astro IIDC.


No, there is no supported method for selecting a specific port. Most people are using the single port US 28X model port, so it wasn't deemed as being necessary.


I have a 4 serial port keyspan usb-serial adapter and Astro IIDC doesn't propose any option

to select a different port and choose port #1 by default (event if it's already in use).

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.


We will look into adding this feature in the 3.0 release of Astro IIDC.


HTH..
