I'd probably use sed.

command | sed 's/.*PORT =/PORT =/; T del; s/).*//; t; :del d'

What was the output that was produced, or the errors generated? Both work for me on Linux.

PORT = 2100
OK (40 msec

The output has multiple lines . need just value of port ( in this case 2100) .
Appreciate your help.
