USB to RS232 cable problems

[focussys]

I have used X10 successfully for many years and controlled my whole house via a CM11A controller. This controller connected to my PC through a serial port and could be easily programmed to change lights etc. Since the old PC died and I have bought a new one there is no serial socket on it. I got a cable adapter recently and installed the driver. After some jigging to get the device to be on COM2 (CM11A only allows 1 - 4) I still can't program the CM11A. The Activehome software fails its communication test to COM2. I downloaded a serial port monitor and it looks like bits are sending. Now I'm stuck! Any ideas out there?

Look in Properties for COM2 and check the baud rate, parity, number of bits, etc is configured properly. The manual I found says 4800 baud, no parity, 8 data bits, 1 stop bit.

Hi Frank4d

Thanks for the reply.

I have checked all you say and they are correct, although I don't understand what to set for flow control.

I have downloaded an free piece of software called X10 Controller and it connects to COM2 OK, but no controls are strored.
Activehome continues to not recognise anything plugged in.
