I have a New Zealand modem and I am trying to set the number of rings before it answers to 8. To do this I am changing register 'S0'. I am able to change this to any number between 0&4, but any higher and it ignores the command. Any ideas?
In order for this modem to be approved in New Zealand, we were required to set this modem to allow no more than 4 rings. If you try setting it to anything higher than 4 it will still only set it to 4.
