Dreamboard

Hi Friends,

My DreamUp software wouldn't even start on my laptop because it says "can't find any COM port".

I have a pretty good laptop and I'm sure there can be done something. Do I have to do something in my Laptop's setup to enable a COM port and reroute it to any of the USB ports? Can I then upgrade the firmware of my DM800HDPVR by this?

Thanks, regards, Zlatko

You need to install the USB to UART driver in order to have a virtual COM port available: http://www.dream-multimedia-tv…/dm-800-hd-se-information

Many thanks. Can I then use USB cable in stead of a null modem cable to connect to the DM?

No, only the newer models (800se, 500HD, 7020HD) have an USB-to-COM Adapter included. You still need a COM-Port and a nullmodem cable.

But you can buy a USB->COM Adapter for your laptop and attach the nullmodem cable to it.

Anyway: If you just want to flash a new image, then you won't need any nullmodem or DreamUp. You can flash easily via network: http://www.dream-multimedia-tv…flashing-firmware-browser
