- There was just a thread about this last month in this group, if I recall.
- To sum up:
- If you use pulse dialing rather than tone you need to set the pulse
- make/break ratio to match the country you are in.
- The pattern for incoming ringing may confuse the modem, but of course
- if your calling is all outbound who cares.
- You will need an adapter cable or plug for each country.
- Some countries say you can use only "approved" modems, but that is only
- for protectionism and not electrical safety. A modem that has US FCC
- approval will be safe anywhere.
