Figure 5-4 Typical IspConnection object logic.
In the example at the right, a
schedule object controls the
connect/disconnect schedule
of the IspConnection object.
A binary log object logs each
change of state (from active
to inactive).
The JACE successfully
connected to the ISP as a
client, with a baud rate of
48 K.
This example shows that the
modem successfully
connected to the ISP at 14:19
on 3-April. However line
problems forced a hang up.
Since the schedule showed
“Active”, the daemon tried to
reconnect until an “Inactive”
status was received at 15:15
when the active schedule
expired. The daemon made
its last connection attempt at
15:13 on 3-April.
The current state of the
modem is listening, because
the dialOutOnly parameter of
the ras.properties file is set to
false.
Figure 5-5 GxPage use of IspConnection object outputs.
This simple GxPage
illustrates the use of GxText
objects linked to each output
of the IspConnection object.
