Unix Error: "another process waiting on open" message during boot up or when attempting to communicate with the port.
- This is caused by the System booting faster than the ports can download their code and initialize. To solve the problem add:
until sleep 1 < /dev/ttya01
) 2> /dev/null
- at the top of
/etc/rc.d/8/userdef. If there are multiple devices, it may be prudent to replicate these commands for the first port on each device.
