6d6667755e Create struct fsm_parent. FSMs are created with one of these,
and the FSM passes subsequent events to them.

The datalink now hides its CCP from the bundle layer.

f4768038f0 o Remove the global CcpInfo. It's now part of the datalink.
Struct bundle will have its own struct ccp in the future
  too.
o The ``set stopped'' command now requires context and doesn't
  work on the IPCP FSM.
o Check if it's time to break out of our top level loop before
  doing a select - otherwise, we'll select forever :-(
o Remove `struct link'::ccp (a temporary hack).  It turns out
  that IpStartOutput() calls link_Output() and link_Output()
  incorrectly calls StartOutput() (really modem_StartOutput)
  requiring the ccp knowledge so that it can call
  IpStartOutput()...  The end result is that the whole IP
  output queue gets dumped into the modem output queue
  and a pile of physical writes are done prematurely.  This
  makes the (original) code in main() actually work in that
  it would not bother selecting() on the tun descriptor when
  our modem queue length was 20 or greater.  Instead, we now
  make that decision based on the overall queue length.

  This will need improvement later.

73a13b5c4d Cosmetic: Group configuration items in struct datalink. 1998-02-17 19:28:49 +00:00

c7cc50305f Add datalink state DATALINK_READY to indicate when the datalink
is available, but LCP hasn't yet been started.  We get to this
state in ``term'' mode.
Remove PacketMode().  LCP startup and shutdown is now controlled
by the datalink.
Add ``show links'' command.
Make ``close'' capable of running with and without a context.
Make ``down'' require a context.
Make ``set parity'' and ``set rtscts'' use the correct context.

c5a5a6ca93 Sort out (fix) the `term' command.
datalink_Up() can now be told to skip the dial/login/hangup
scripts and can be told whether to enter packet mode when
entering the DATALINK_OPENED state.

e718d1d7d8 Move the redial timeouts and max tries into struct datalink. 1998-02-16 19:11:10 +00:00

abff9bae14 Move the reconnect timeout and max tries into struct datalink. 1998-02-16 19:10:44 +00:00

5b8b8060c1 Move the dial, login and hangup scripts into struct datalink.
Don't set these scripts in -direct mode.
Always set reconnect_tries to zero for -direct mode.

3006ec67fe Create struct datalink.
This is a type of physical link that can chat and talk
LCP & CCP.  A bundle contains a list of these (only one
in the list for the moment).

The datalink is a type of descriptor, and dials, enters
LCP (& does CCP), kicks the bundle when its FSMs do
something interesting and does the hangup chat script
on the way down.  It also handles redials and reconnects.

There are lots of loose ends, and probably lots of bugs,
but the data structures are getting there !
