US modems will work fine in the UK, just be sure that it supports the CCITT
protocols as well as the Bell protocols.  Must current modems do.

Tone dialing is the same allo over the world.

The wall line jack requires a different plug, but thr telset jack is usually
a RJ-11.  However, instead of pins 2&3 being tip and ring, in the UK it is pins
1&4!
