POCSAG
POCSAG is an asynchronous protocol used to transmit data to pagers. The name comes from Post Office Code Standardization Advisory Group, this being the British Post Office which used to run nearly all telecommunications in Britain before privatization.
The main alternative to POCSAG is FLEX, which uses higher speeds and a four level modulation method. GOLAY, TONE and ERMES are previous paging protocols.
The family of POCSAG protocols can operate at three speeds, 512 bits per second (the original specification speed) is the base standard.
With Super-POCSAG 1200 bits per second, or 2400 bits per second transmission rates are possible. Super-POCSAG has mostly displaced the POCSAG in the developed world but the transition is still in progress.
The related Flex Synchronous protocol achieves speeds of 1600 bits per second, 3200 bits per second and 6400 bits per second.
How it works
The modulation used is FSK with a ±4.5 kHz shift on the carrier. The high frequency represents a 0 and the low frequency a 1.

Bukowski
by: Modest MouseWoke up this morning and it seemed to me,
that every night turns out to be
A little more like Bukowski.
And yeah, I know he's a pretty good read.
But God who'd wanna be?
God who'd wanna be such an asshole?
God who'd wanna be?
God who'd wanna be such an asshole?
Well we sat on the edge of the river,
the crowd screamed, "Sacrifice the liver!"
If God takes life, he's an Indian giver.
So tell me now why, you'll tell me never.
Who would wanna be?
Who would wanna be such a control freak?
Well who would wanna be?
Who would wanna be such a control freak?
Well see what you wanna see. You should see it all.
Well take what you want from me. You deserve it all.
Nine times out of ten our hearts just get dissolved.
Well I want a better place or just a better way to fall.
But one time out of ten, everything is perfect for us all.
Well I want a better place or just a better way to fall.
Here we go!
If God controls the land and disease,
keeps a watchful eye on me,
If he's really so damn mighty,
my problem is I can't see,
well who would wanna be?
Who would wanna be such a control freak?
Well who would wanna be?
Who would wanna be such a control freak?
Evil home stereo, what good songs do you know?
Evil me, oh yeah I know, what good curves can you throw?
Well all that icing and all that cake,
I can't make it to your wedding, but I'm sure I'll be at your wake.
You were talk, talk, talk, talkin' in circles that day,
when you get to the point make sure that I'm still awake, OK?
Went to bed and didn't see
why every day turns out to be
a little bit more like Bukowski.
And yeah, I know he's a pretty good read.
But God who'd wanna be?
