The telephone modem at the weather station has answered but cannot establish a synchronous connection with the computer modem. One possible cause is that the baud rate (data transmission speed) of one or both modems is not at 1200 bps. If the computer is equipped with a Win Modem, this may be the case. Another reason could be that the 2 modems are not compatible with one another. Check if your modem works at a different speed or try connecting a hardwired modem that will step down to 1200 bps (either on the motherboard or connected via the USB port).
Note: This message is generated by the modem. It gives no information about the WatchDog Weather Station. It may still be possible to connect to the station via direct connection.
