usb to serial adapters?
Ive got a bit of a problem here. I was going to use a serial relay to start my laptop when my mobile connected to it got a txt. the problem is that ive noticed my laptop doesnt have a serial port... doh!
Basically i want to be able to txt the computer and it send me back information or do certain things. Now I could connect the phone (Nokia 6310i) via a usb cable and that would be fine for the communication. The problem is then how to boot the pc from the phone.
I considered running a wire from the com port used for texts on the phone to a realy which would trip my power cable. but then if i text it again i realised it would kill the pc.
Im out of my depth here but is there anything i could use to do say an if statement? for example... 'if pc = off then power it' etc.
Ive got a spare pcmcia port if that helps, and parallel. its not got a modem so i cant do wake up on ring and it doesnt suppose wakeup on lan.
any ideas would be greatly accepted! cheers fellas

thats quite interesting, i will deffo look into that as then there is the possibility of changing how long you would press the button for. and thus a quick burst from a phone wouldnt change anything.Originally Posted by Rundell
oooh, i could have quick burst of power to turn it on as normal, and then a hold for 4 seconds to turn off. interesting, i shall research more but that makes a bit of sense. cheers!
I wanna try to do something like this...
I've been thinking of a way to do this via WOL (Wake On Lan)
right, my plan is now the following:
nokia 6310 connected via usb to pc, a cut in the usb cable routes any data through a relay which if detected will flick the power line and start the pc.
then after its started i can send txt commands to the pc.
to shut the pc down i can text it too, no need for the relay.
and to shut it down whilt im in there i just do it through road runner.

Can you give us a better idea exactly what your doing/have done to set this up, as it's something that's on my "must do" list! How does the phone/pc work out what is a text to shut it down, or a text to do something??
Any pics or diagrams would be very helpfull,
Cheers in advance.

dave, is that a 6310i?
if u have bluetooth, u can power on via cable, and talk via bluetooth. Might make things simpler to communicate via seperate channels. tho bluetooth maybe a little flacky.
How about wiring the ringer to a relay? that way text's can be silent to ignore switching on via sms. and you could control via serial?
just some ideas.
why not wire a second (normally closed) relay inline with the first and set this to open when the computer is powered up, that way the link to the power button is broke whenever the computer is on and any further texts received by the phone would not trigger the power button.Originally Posted by davebateman
hey DaveC thanks! you just solved how I will use the IBUS to power my car, rather than the ignition switch! That way when I use my keyfob to open the car, the pc can start powering up. nice 1
