The following sections explain the modem initialization strings used by the soft-
ware and what each part of the string means. Do not change the initialization
strings unless you understand what impact it will have, otherwise the software
may not be able to work with your fax/modem.
Station Modem Initialization String
The software automatically enters the following modem initialization string,
which should work with most modems: AT E Q V X4 S7=60. The individual com-
ponents of the string have the following meaning.
▲
AT
This string precedes all Hayes commands.
▲
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 0-7 and 10.
▲
S7=60
Tells modem to wait a maximum of 60 seconds for remote modem to answer
and issue a data carrier.
The software can perform some troubleshooting of modem problems in the form
of error messages. In order 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 WeatherLink
Software, you may need to re-initialize the modem using the modem string expected by the
other program.
Auto Fax Modem Initialization String
The software automatically enters the following modem initialization string,
which should work with most fax modems: AT H &D0 E0 V1 &H1. The individ-
ual components of the string have the following meaning.
▲
AT
This string precedes all Hayes commands.
▲
H
Hangs up the modem if it is still connected.
▲
&D0
Overrides the default response on the data terminal line (DTR).
▲
E0
Disables command echo.
