##                            
## PURPOSE:
##        For a given NNS 'TelecomID' (like t123654 or h12345),
##            1) checks for IP address in a user specified NNS DSN domain,
##               like 'prt.nns.com' or 'nns.com',
##        and
##            2) if IP address exists, pings it to determine if the
##               device (print-server box/card) is responding.
##

## CALLED BY: 'prtplt_mgr'   script in  $FEDIR/scripts
##                                where FEDIR=/apps/nns_com/fea
##            actually, by 'prtplt_mgr.chestdef'  in  $FEDIR/scripts.
##
##  I.e. called by clicking on the PrtPlt_Mgr menu item (toolchest drawer)
##
##              'CHECK_NET_CONNECTION; of TelecomID'

## MAINTENANCE HISTORY:
## Written by: Blaise Montandon O06  4Jun1999 Based on prtplt_sho_Qstatus
##                                            in $FEDIR/scripts/
## Updated by: Blaise Montandon O06 29Apr2000 Chgd from '100% packet loss'
##                                            to '100.0% packet loss'.
## Updated by: Blaise Montandon O06 27Jun2000 Removed -s & -T parms from ping.
## Updated by: Blaise Montandon     19Jul2001 Chg GUI to get 'domain' as well
##                                            as 'telecomID' from user.  I.e.
##                                            allow for 'nns.com' domain (or
##                                            other) as well as 'prt.nns.com'.
