Perhaps kermit is being misused.  If you terminate it without hanging up
and before starting pppd, and then try to start pppd, then there will be
a race between pppd and getty to grab the port.  getty will probably win.
If you terminate kermit normally then it will hang up.  Then there should
be no races, but kermit will be of no use for starting pppd sessions.

These problems may be avoided in many different ways:
1. suspend kermit instead of exiting from it.
2. some kludge to hold the device open after exiting from kermit.
3. run kermit from inside pppd.
4. run something simpler than kermit from inside pppd.
