Are there any problems associated with using modem connections between the UK and the USA due to the difference in the audio frequencies utilised? thanks, ivor

At 2400 baud and above, things are pretty much standardized, but this is still a problem at 1200. Most Hayes-compatible modems offer a software switch (ATB0/ATB1) to select between the Bell 212 standard used in North America and the v.22 standard common in Britain. Really smart ones will shift to match the answering tone regardless of setting, but this is probably not as reliable as setting your modem ahead of time to match the receiver. v.23 modems are virtually unknown in North America--don't even bother trying to connect with one of these. You may find that transatlantic phone calls are subject to a lot of line noise. You *may* be able to avoid both this and modem-tone conflicts if your destination is reachable through a packet-switched network like Tymnet or Telenet.... Dave
