/*
* 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.
