Re: LF: Windows software to drive a relay at a given time?

[Andy Talbot <andy.g4jnt@gmail.com>]

Just in case it matters, I initially test for all valid COM ports by opening and closing each in turn,  then testing for an error.    

If that causes problems to anything on another port that has not yet been opened, like another PTT control,    it will briefly 'blip'

Any COM port already open will get rejected by this test so no adverse effect there.

It lets you abort the on time using the [esc] key

Source code is in there as well 

All in PowerBasic, command line compiler version

(By far the nicest way to programme simple things that don't need whizzy windows interfaces)

Hello LF'ers


Software to close a relay at a given time, perhaps via the serial port?


I am looking for some simple software to enable, at a given time to
within a second or so, derived from the PC time, activate a relay or
semiconductor switch possibly via a true serial port, of which i have
several spare. Does anyone know of anything like that please? Ideally
it would be able to open the relay at a later time. Just two time
based changes of state would be adequate in a 24 hour period. Thanks.
OS is MS Windows 7 64 bit Pro.
