I'm not familiar with that type of modem. I work with externl modems. Sometimes we need to set the S0 register to a value higher than 0(zero). 0 is never answer 1 answer on 1 ring 2 on 2 rings etc.
Here is how I do this
This shows an example of when the S0 register is set to 0 (zero).
When set to zero the modem will never answer.
reverse telnet to modem
OK
