Weird keyboard behavior

Dec 21, 2020 59 Replies

I've got a RPi4 with USB keyboard and mouse. It all works fine but there's a very odd thing, which took me awhile to figure out: I have to press @ to get " and I have to press " to get @.



Is that a Pi thing? Linux? Faulty keyboard? International settings? I've never seen such behavior. Aside from that it seems to be fine.


If @ is on shift-2 you have an American keyboard. " on shift-2 is English. Set the keyboard type in raspi-config/Localisation Options.

That's an international keyboard thing IIRC.

I've lived with this for some time, but on a BeagleBoard running RISCOS. A friendly oddity that comes and goes, sometimes correctly, sometimes wrongly :-)

On Linux run raspi-config and localisation options, keyboard, and choose US.

On RISC OS use *Keyboard USA, and *Configure Country USA to remember the setting on reboot.

What makes it come, and what makes it go? I can't understand why it would change except as a result of a deliberate action on your part.

Life is full of events that sporadically come and go without deliberate actions - as atm my 'phone line which has been dead for two weeks, but is able to have WAN connectivity, and for which Techies cannot see any reason. I am a user, and don't deliberately take actions to violate things that are working peacefully.

the phone line has nothing to do with the WAN, except it shares the same physical line. Hopefully someone will find and solve the issue for you. I spent >10y in phone provisioning - I've seen a lot - nothing can surprise me anymore :) especially since Indian companies do the development and support :P

If it's what we call an ADSL connection here in the UK then symptoms of 'no phone' but 'internet working' are not that rare. If there's a physical break in the wires then your POTS phone will stop working but because the internet connection uses (moderately) high frequencies the break in the wire just attenuates the signal somewhat but doesn't stop it working completely.

I think nowdays the providers use SIP over dedicated SIP network. If there is a POTS somewhere it would be rarity. Even the middle age NCS are being decommissioned. It could be anything from some DB issue preventing the device to register, wrong boot files or faulty firmware upgrade - faulty equipment between the device and the provide - anything.

There's lots of POTS phones still here in the UK, at least the last few miles is still a copper (or if you're unlucky) an aluminium pair.

Chris Green

This is true, but the voice switches changed. I worked for a provider in Ireland and the DMS100 was decommissioned 5y ago. What stayed is the CS2K which would do the switching for your two copper or aluminum pair wire. A friend I met in another project worked for Virgin Media in the UK, but I stepped back and I don't know what kind of switches they use there. So basically there are no POTS (analog) lines on the switches (at least in half of Europe where I worked). I bet you have a phone with buttons and not with the old rotary dial. The reason to decommission the POTS was the maintenance and electricity cost not to mention the size.

Yes, but since the last mile or two is still copper the explanation I gave for how you can have no telephone service but have an internet connection still stands. A break in the 'last mile or so' of copper will produce those symptoms.

When I had FTTH installed here the first thing they did (after erecting a couple of poles) was run copper to the house with a POTS service on it, then a week or so later another crew turned up and installed the fibre. The POTS service is active but never used. It would make a lot more sense if the fibre termination was powered by the 50V on the POTS line but it's powered by being plugged into the mains.

I assume the dial tone showed up as a charge? Back when DSL started out in 1999-2000, the local exchange carrier required an active phone line to deliver DSL, whereas the people who resold DSL services could provide DSL only. The extra charge, combined with stonewalling the resellers and making it difficult for them to provide service effectively killed off a couple of the carrier's own customers.

There's a 48vDC current running across the copper pair in a POTS line. It's called talk battery or loop current. I think the original poster was talking about powering the fiber terminator over it.

Comcast, my cable provider, offers an internet/telco modem that provides dial tone. There's a spot in the modem to install a small battery backup, but I'm tempted to throw it on a spare desktop UPS and see how long it'll run.

I still have one 2500 set left over from my days as a Phone Guy, keep it near the modem *just in case*.

It's that time of year, the first rains of the season, when the overhead telephone lines get wet, terminations corrode, and line quality goes to hell.

Calling Pac Bell, complaining about line noise, and being told the solution to getting what you've already paid for was to pay more.
