Hi All,

I recently purchased a freeview box that can be managed using a NULL modem.

I dont know what one of these is, but went to my local comuter store to pick on up and got home to find i only have USB's interfaces on my laptop, so i bought the item below;

http://www.aria.co.uk/Products/Cables/USB/Firewire/Printer+Cables/USB+to+Serial+(RS232)+cable?productId=29931&page=2&rqcType=


I installed the USB drivers and it's showing up in device manager as USB-SERIAL CH230 (COM3), but when i try to connect the freeview box it times out.


Any suggestions on what i might be doing wrong?

You might need a null modem adapter on the end of the cable.

Sorry, what program are you using to connect? Are you using something like hyperterm or putty?

I took the box around my friends house to use his PC (that has a serial port) and it turns out it was an issue with USB-to-serial.

I've ordered a usb-to-serial null modem cable from eBay, so will use taht when it arrives.


Many thanks
