Modem Initialization String
34
M o d e m I n i t i a li z a t i o n St r i n g
The software automatically enters the following modem initialization string in the
serial port settings dialog box, which should work with most modems:
AT &F S7=60 E Q V X4.
The individual components of the string have the following meaning.
▲ ·AT
This string precedes all Hayes commands.
▲ ·&F
Resets modem to factory defaults
▲ ·S7=60
Tells modem to wait a maximum of 60 seconds for remote modem to
answer and issue a data carrier.
▲ ·E
Turns echo off.
▲ ·Q
Tells the modem to return result codes.
▲ ·V
Tells the modem to return short form result codes.
▲ ·X4
Enables result codes 0 to 7 and 10.
The software can troubleshoot some modem problems by presenting error mes-
sages. For the software to provide error messages, any modem initialization string
you enter must contain the E, Q, and V strings.
Note: If you use another communications program after using the modem with the Weather-
Link Software, you may need to re-initialize the modem using the modem string
expected by the other program.

? The barometer graph on the Bulletin does not “fill in” completely.
When you first load the bulletin, the barometer graph will only fill in com-
pletely when you have data in your database for the last six hours. Make sure
of the following:
▲ There is data in your database for the span of the barometer graph.
▲ The time and date of the stored barometer data is correct in your database.
▲ The time and date on the PC is correct.
▲ The time and date on the weather station are correct.
? No wind direction reading (or dashes instead of a reading) appears in my data-
base.
Be aware that if there is no wind speed when the direction is being sampled,
wind direction is not recorded. During intervals with very little wind speed,
no direction may be recorded.
CAUTION: Since high wind speed is sampled more often, it is possible to have a high
wind speed but no wind speed or direction.
