NTP Software Installation and Configuration

6.7.2 Set Up Device Links
NTP attempts to open the I/O file /DEV/ACUTIMEX, to communicate
with the Acutime NTP reference clock. The x represents the unit
number of the reference clock in the configuration file.
A symbolic link /
DEV/ACUTIMEX must be set up to point to the correct
host serial port. This is typically performed by a sequence of shell
commands similar to:
cd /dev
ln -s ttyS0 /dev/Acutime0
Creation of a symbolic link for Acutime NTP reference clock unit #1
connected to the second serial port, ttyb, is shown below for a
Solaris system. The link for unit 0 has already been established and
remains unused in this configuration.
