US telephone equipment uses a make/break ratio of 39/61 %. That ratio is 33/37
% in some parts of Europe. This effects pulse dialing.
A lot (most?) of modems available in Ireland and the UK support the AT command
set. I can't say what the situation in Italy might be. The fact that there was
no English language docs might indicate an Italian "standard". 
I have two different card modems that I bought in the US, and they work fine 
here, when the jumpers are set to CCITT mode. (ie V standards.) 1200 and 2400 
baud work fine, but 300 is out. (big deal)
