COM1 unavailable (HP true RS-232 )
I am disappointed .
I bought the HP ProBook laptops thats still to date are delivered with windows 7 professional & a real physical COM port.
I need it for serial-interface communication instead of fooling around with usb-adapters.
But to my surprise,the com port seems to fail on me! And the virtual-usb adapters works better.
Very often the com1 just goes unavailable:
cmd
Code:mode com1
-unavailable for the moment
Also when listing com ports within pshell it appears, but when check mode comX you should se
all of its settings, like baudrate etc :
When connecting my external usb-adapter it appears as COM10 and works fine. I do believe that it has to do with the so called XP MODECode:PS C:\Users\rihtt> [System.IO.Ports.SerialPort]::getportnames() COM1
I Run the virtual XP MODE PC on this windows7, and they share hardware. The com1 is also listed within the virtual machine but it doesnt work.
Is there anything to do at all, or is this hardware issue thats the manufactor H P should do?
