selecting the device from the device list and clicking
<B

is configured not to start at boot time by default. Edit its
configuration to modify this setting. Compression, PPP options,
login name, password, and more can be changed.

its <B

it from the device list, and click the <B

button. If the system is configured to activate the device when the
computer starts (the default), this step does not have to be performed
again.
