ttystat -- Command

Get terminal status
/etc/ttystat [ -d ] port

ttystat checks  the status of the specified  asynchronous port in directory
/dev. It normally just returns an  exit status that indicates the status of
the port.  The option -d tells  ttystat to print the status  of the port on
the standard output.

Example

The following example prints the status of port /dev/com2r:

    /etc/ttystat -d com2

If /dev/com2r is enabled, ttystat prints:

    com2r is enabled

ttystat finds the port status from the /etc/ttys file.

disabled.  It returns -2 if an error occurs.
