Dialing

If there is no entry for Phone Number, then every time you choose an
option that opens the COM port that connected to a modem, EcoWatch
will ask you for a phone number. Timeout specifies how long in
seconds EcoWatch will wait for the phone to answer.
Use the Dial option to select Tone or Pulse dialing.
This is where you choose a default port for communicating with a sonde and
default capture files for each sonde port. This tab addresses several COM port
settings not covered on the other two tabs.
 Default Capture File
While communicating to a sonde in terminal mode using the Sonde
command, you may want to capture measurements to a file. You may
type in a default file name in the accompanying text box.
If you specify a file name here and select the Use on Capture check
box, then whenever you capture data, the program will write to that file
without first asking you to confirm. If you specify a file but do not
select the check box, then you will have to confirm that this is the file
you wish to have your data written to before starting to capture.
