Adding Caller ID Support
Caller ID support can be enabled by adding the following entries: EnableCallerID, CallerIDPrivate, CallerIDOutSide and VariableTerminator.
The EnableCallerID entry is the command string that Unimodem sends to the modem to enable Caller ID. For example, the SmpVoice.inf file contains the following entry:
HKR, EnableCallerID, 1,, "at#cid=1<cr>"
The CallerIDPrivate and CallerIDOutSide entries define characters that the modem returns for Caller ID information that is blocked because it is private or originates outside the area. For example, the SmpVoice.inf file contains the following entries:
HKR,, CallerIDPrivate,, "P"
HKR,, CallerIDOutSide,, "O"
The Caller ID information that the modem returns is variable in length. Therefore, string termination characters must be specified. For example, the SmpVoice.inf file contains the following entry:
HKR,, VariableTerminator,,<cr><lf>
