Subject: tip fails to cycle past a "dead" device.
Index: /usr/src/usr.bin/tip/hunt.c 4.3BSD
Description:
The following bug report and fix are brought to you by Richard Wolff.
tip fails to cycle through multiple modem devices (dv entry in
/etc/remote) if a particular device is found to be "dead". Cycling works
properly only when a device is "busy".
Repeat-By:
Have multiple entries for dv in /etc/remote. Arrange for the first
device in the list to be "dead" (powering-off the modem works for me). Try
to tip and notice the "all ports busy" message.
