Ok, so I've been using dialup forever.

This sucks. And downloading WU's every night isn't helping.

I heard, that in Windows XP, you can go Control Panel>Modem>Properties>Advanced and add "&f" to the extra settings dialog to speed up your dial up.

I did this.

Origionally Windows said I was connected at 49.2k. After makign this change, it now says 115.2k.

Am I really connected this fast? Or does the modification I made just make the computer think you're connected this fast?

&f resets the modem to factory settings.

"Back in the day" there were 300 and 1200 baud modems. When a modem connected at 300 baud, it reported the speed at 300 baud and the computer had to shift the UART to 300 baud.

Later, when modems got faster and started doing compression, the port speed needed to be faster than the actual connection speed, so the modem intentionally "lied" while terminal programs were updated so they could be locked.

115.2k is the fastest speed that a normal PC serial port can run.

So, instead of reporting 49.2k (which is the real connection speed) it's reporting the port speed, which doesn't mean anything.

There are two speeds to a connection.

1) The computer serial port to modem speed. which is probably what you are reading.
2) The modem to modem speed, via the phone line, which might get up to 40k +, depending on the phone line quality. 56k modems can't get to 56k speed do to phone company & government restrictions.

yeah, I am fairly certain that government restriction is 50K. I close enough..I could be wrong..I am going off fuzzy memory.

I should have added:

The modem does data compression, so the computer to modem data speed should be as high as can be set with out errors creaping in. That way the modem doesn't get starved. :-)

Well, I am not concerened about how fast the modem talks to it's own machine, rather, I would be more concered with how it modulates/demodulates the sound over the phone line. You can have a bad ass modem but if the phone line causes line "noise" to get introduced into the modems own sound...you get errors.
