#***********************************************************************************
#*  Description:   This program queries the system to determine the state of the   *
#*                 network interface on a Tru64 system.                            *
#*                 To test the status of the network link, the local gateway is    *
#*                 pinged 3 times.                                                 *
#***********************************************************************************
#*  Parameters:    checknic [[NIC] [-s|-d|-c]]                                     *
#*                 NIC  =  the network interface eg tu0 or ee0                     *
#*                 -s   =  display short (1 line) output                           *
#*                 -d   =  display detailed output                                 *
#*                 -c   =  change port speed of the NIC interface                  *

#*                 13 Jun 2002 - release 1.4                                       *
#*                 13 Jun 2002 - Tested ok on v4.0F and v5.1A                      *
#*                 12 Jun 2002 - added extra parameter processing                  *
#*                 12 Jun 2002 - added checking for local gateway router by ping   *
#*                 02 Jun 2002 - added code to modify port speed                   *
#*                 16 May 2002 - added front end to program                        *
#*                 24 Apr 2002 - modified code to procedural methodology           *
#*                 15 Mar 2002 - created v1.0 to check the port speed              *
#***********************************************************************************
#*  Future Devs:   1. Verify the ping is being sent through the interface chosen   *
#*                 2. fix up change port speed logic and  questions                *
