This section includes points to look at if the Direct Modem connection fails to dial and synchronize with the NIST timeserver. The phone line is not configured for outbound dialing. The phone line or extension in use is restricted from dialing a long distance number. The NIST modem should answer the call. Turn handshaking on or off on the Direct Modem Connection screen.
Some modems require that handshaking be set to allow the modem to dial.
Settings can be first tested by using the Modem Test Screen. Try turning the RTS and DTR enable on or off, adjust both the Type Handshake to None or RTS . Try a different Attention string. If the Attention string is invalid for the modem in use, then the modem will not be able to continue. Try the different Attention strings available in the Templates on the Direct Modem Connection form.
