content: maybe you are trying to open the wrong port number.check in hardware what serial ports you have - then see which one the software is trying to open.

content: Something is waaay off here.That multimeter has a USB 2.0 interface. There's absolutely no reason to muck around with "serial over bluetooth" or other COM ports.If the drivers and software are installed correctly, it should be plug and play.Why your software lets you select COM ports is a mystery to me.If it's really designed to emulate COM over a USB interface, it should be taken out and shot.

content: most usb stuff just converts to serial internally - there arent many usb microcontrollers around - not compared to ones with uarts anyway.plus it's a lot simpler in software.
