NAME

SYNOPSIS

9       #include <net/misc.h>
10
11       void DeviceOffline(int flag);

DESCRIPTION

14       The  DeviceOffline()  function  turns the packet driver offline so that
15       other application may utilise the resources that it is using.
16
17       For example for the built in SLIP driver,  turning  the  device  online
18       prevents  polling of the serial port for incoming bytes and the sending
19       of queued packets, thus allowing another program (e.g. Terminal) to use
20       the serial port.
21
22       The  parameter  flag  specifies how the device is to be turned offline,
23       with current device drivers this has no  significence.  However  it  is
24       envisaged  that the value NOHANGUP the device will simply suspend send‐
25       ing and receiving packets. Whilst with HANGUP the  device  will  hangup
26       the line and terminate the telephone connection.
