Programming - Can't find file/COM1

by Manicotti on Fri Nov 12, 2010 9:28 pm

Greetings - I'm trying to program the MiniPov3 on Win7 (built from a kit), and trying to program it using a USB serial port adapter keeps bringing up this error message:

I'm not sure what's going on here - is it not recognizing that it's plugged into USB port COM1, or what? The driver on the serial port adapter is up to date and I even changed its properties to COM1, for what that's worth. The MiniPov itself is working fine otherwise - turning on the battery pack causes the LEDs to light up in sequence as preprogrammed. Any feedback is appreciated.

(edited to add a more useful screencap)

I went through those threads, but I'm not sure how to apply that here. Where would I even check for the existence of the COM1 device, let alone access whatever might be using it already? The connections seem solid and so is the file path, so why can't it find the file?

If you were able to change the properties on it, then it exists.
The most likely problem is that some application used it, then neglected to close the handle.
Close all applications and try again. If that fails, reboot and try again.

Done and done, and apparently that's all it took. Thank you both for your help.
