This is a bit off topic but likely someone in the group has already done
this:
We have an audio fail alarm which monitors outgoing audio and as well as
sounding a local hooter, has a series of contact closures for 'no audio'
'someone has hit alarm reset' 'standby programme playing' ' normal
audio restored'.
I had thought that wiring the contacts to a serial port and finding a
script that would monitor the contact closures would be easy.
Over confidence 1 Success 0
There must be some code somewhere which allows ttyS0 to be used as a
contact close alert.
I have googled and searched what code books I can find and I am stuck.
Any help, humorous comments, pointers to code, will be appreciated.
I would have thought the serial port would have been an obvious external
control point, but mostly it's where I can plug expensive external boxes.
