This behaviour is required for send-only environments in which a
process is not run (and the modem would be known to be in a
properly initialized state).
and cleans up any resources it controls; this is the mechanism
to abort a job while it is in progress.
Many aspects of
operation are controlled through a configuration file.
The configuration file is located in the spooler hierarchy
subdirectory and is named
for detailed information on the contents of configuration files.
The protocol which must be used for a specific service provider
is controled from the
as a configuration parameter specification that is interpreted
after reading the per-device configuration file.
For example, ``-c sessiontracing:0x4f'' would set the
configuration parameter to ``0x4f'', overriding any setting in
the configuration file.

A device identifier is formed from a device filename by removing
