调用RASAPI判断modem连接状态(71分)

我调用RASAPI判断出的modem连接状态如下：<br>&nbsp; &nbsp; &nbsp; RASCS_OpenPort:<br>&nbsp; &nbsp; &nbsp; RASCS_PortOpened: &nbsp; &nbsp; &nbsp; <br>&nbsp; &nbsp; &nbsp; RASCS_ConnectDevice: &nbsp; &nbsp; <br>&nbsp; &nbsp; &nbsp; RASCS_DeviceConnected:<br>&nbsp; &nbsp; &nbsp; RASCS_AllDevicesConnected:<br>&nbsp; &nbsp; &nbsp; RASCS_Authenticate:<br>&nbsp; &nbsp; &nbsp; RASCS_AuthNotify:<br>&nbsp; &nbsp; &nbsp; RASCS_AuthRetry:<br>&nbsp; &nbsp; &nbsp; RASCS_AuthCallback:<br>&nbsp; &nbsp; &nbsp; RASCS_AuthChangePassword:<br>&nbsp; &nbsp; &nbsp; RASCS_AuthProject:<br>&nbsp; &nbsp; &nbsp; RASCS_AuthLinkSpeed:<br>&nbsp; &nbsp; &nbsp; RASCS_AuthAck:<br>&nbsp; &nbsp; &nbsp; RASCS_ReAuthenticate:<br>&nbsp; &nbsp; &nbsp; RASCS_Authenticated:<br>&nbsp; &nbsp; &nbsp; RASCS_PrepareForCallback:<br>&nbsp; &nbsp; &nbsp; RASCS_WaitForModemReset:<br>&nbsp; &nbsp; &nbsp; RASCS_WaitForCallback:<br>&nbsp; &nbsp; &nbsp; RASCS_Projected:<br>&nbsp; &nbsp; &nbsp; RASCS_StartAuthentication:<br>&nbsp; &nbsp; &nbsp; RASCS_CallbackComplete:<br>&nbsp; &nbsp; &nbsp; RASCS_LogonNetwork；<br>&nbsp; &nbsp; &nbsp; RASCS_Interactive:<br>&nbsp; &nbsp; &nbsp; RASCS_RetryAuthentication:<br>&nbsp; &nbsp; &nbsp; RASCS_CallbackSetByCaller:<br>&nbsp; &nbsp; &nbsp; RASCS_PasswordExpired；<br>各代表什么含义？:就只有这么多分了。<br>
