* This is the logic behind the reconnect variables:
|
|
* We have four reconnect "states". We start off not requiring anything
|
|
* from the reconnect code (reconnectState == RECON_UNKNOWN). If the
|
|
* line is brought down (via LcpClose() or LcpDown()), we have to decide
|
|
* whether to set to RECON_TRUE or RECON_FALSE. It's only here that we
|
|
* know the correct action. Once we've decided, we don't want that
|
|
* decision to be overridden (hence the above reconnect() macro) - If we
|
|
* call LcpClose, the ModemTimeout() still gets to "notice" that the line
|
|
* is down. When it "notice"s, it should only set RECON_TRUE if a decision
|
|
* hasn't already been made.
|
|
*
|
|
* In main.c, when we notice we have RECON_TRUE, we must only action
|
|
* it once. The fourth "state" is where we're bringing the line up,
|
|
* but if we call LcpClose for any reason (failed PAP/CHAP etc) we
|
|
* don't want to set to RECON_{TRUE,FALSE}.
|
|
*
|
|
* If we get a connection or give up dialing, we go back to RECON_UNKNOWN.
|
|
* If we get give up dialing or reconnecting or if we chose to down the
|
|
* connection, we set reconnectCount back to zero.
