How to change COM port settings using USB-to-Serial Adapter

[smirnoff_rules]

setting to change your com settings

Start -> Control Panel -> System -> Hardware -> Device Manager -> Ports (COM & LPT) -> Prolific USB to Serial Bridge… at this point, take note of the COM number. Use that number when assigning the COM port



in your Device Manager and double click your USB to Serial adapter. Click Port Settings and then Advanced. You should then be able to select the COM port (1, 2, 3, or 4) being careful not to select a COM port already in use on your computer.

if u only have printer and com then change the com one in the drop down box

Some virtual com-port drivers seem to have a fixed com-port number. These drivers mainly use usbser.sys from Microsoft. You can change the inf-file of the device....

[USBtoSer.AddReg] ; AddReg section
HKR,,DevLoader,,*ntkern ;
HKR,,NTMPDriver,,usbser.sys
HKR,,EnumPropPages32,,"MsPorts.dll,SerialPortPropP ageProvider"

The USBtoSer label can be different from your device. The last line is important. Please make sure that msports.dll is included in the inf file. After you have reinstalled the driver, you should be able to change the com-port number.

Mark

I have just bought a usb adaptor for my null modem cable as my laptop doesnt have anywhere for it to plug in but it still aint working. cant see any com ports in harware manager but a usb ser! whatever that means. So I cant flash my dreambox 500c with a new image. I am at a complete loss as how to get round this so I need some simple advice.

Hi
I m in same boat. bought one adapter from ebay. but it didnt work out. tried evrything. later discoverd- after installing the driver for adapter andplugged in USB, windows automatically startts downloaded the driver for adapter, though I already installed one.
so think few these adapters r dodgy, especially bought from china!! and there is no drver support.
well still no luck. goin to fork out more few quid on good one this time.
any progress pls keep updating

A lot of the cheapy USB>Serial adaptors sold on ebay use a TI chipset, and the drivers can be hard enough to find alright. I've attached the drivers I managed to find and I hope they help. They are actually for a USB>Mobile serial phone lead, but they have worked on several non-branded serial leads as they use the same chipset. Cannot hurt to try.
