| 46846 | 2002-05-02 12:25:00 | I was having probs w/ winME detecting infrared serial devices and making heaps of conflict w/ everything.... recently changed down to win98SE and have still had the probs... this may sound really stupid, but is there any chance that this would be interference from a (my) cellphone? I have no infrared gear on my pc... it is just randomly picking this up from somewhere... The closest I've come to a soln is to turn my cellphone off, and/or keep it the hell away from my PC. It actually seems to work, but it really does seem stupid, even to me... my sys is: amd1700+, 256ram, gigabyte mainboard, external dynalink modem, nvidia geforce2, cdrom, cd writer. |

| 46847 | 2002-05-02 12:56:00 | u need a infra-red port on the machine to communicate with ur cellphone. buzzing sound maybe just the interference maganetic to the computer. Can add one via usb port .. RC |

| 46848 | 2002-05-02 14:35:00 | Hi Tim Cellphones periodically transmit to inform the cell site that they are still there, and they are 600 MW of power at around 900 MHZ. VERY probable its getting into the PC by the sound of it, it would cause chaos. If you keep it 2 or 3 metres away it may help. Trevor |

| 46849 | 2002-05-03 04:32:00 | It's hardly likely that a cellphone would transmit an exact sequence which would be detected as a bit pattern which Plug and Pray would identify as a valid IR device. A 600 MW cellphone would (a) have a very short battery life, (b) fry the user, (c) not be very portable. At 600 mW (mW=milliwatt; MW=megawatt), it *might* cause 'errors'. It shouldn't -- the shielding on the computer which is supposed to keep its own noise IN, should keep other noise OUT. There is probably an option in the BIOS setup to disable the IR interface. If you haven't got the hardware, it should be disabled anyway. |

| 46850 | 2002-05-03 05:19:00 | G'day Only analogue phones are 600mW, digital are 1200mW but those power outputs are only reached when the phone is at the outer limits of its communication range. In most circumstances the power output is a small fraction of the full capability. However, digital phones are very invasive in their transmission characteristics and are banned from a lot of computer controlled industrial installations because of their proven ability to interfere with digital data. I prefer not to own or use a digital phone and will stick to analogue as long as I can. When I do have to go digital, I will keep it at least 2 metres from my computer. You might like to try a similar approach, and if it has an extendable antenna, keep that fully extended as the improved signal radiation will lower the required transmitter output. Keep an eye on the signal strength indicator as well and keep the phone in the strongest signal location, provided it isn't on top of your computer of course. Cheers Billy 8-{) |

| 46851 | 2002-05-03 07:06:00 | Most motherboards have an IR port connector on them to add an IR port at a later date. Perhaps the IR port is enabled in the BIOS, even though there isn't a IR interface plugged into the motherboard? | Guest (0) | ||
