What is it?
-----------
This is the FreeBSD ping compiled for OS/2.  There was another compilation
of this program but it did not appear to work with Warp v4 / TCP/IP v4.  This
one seems to work without problem.  (Note: "work" == "works for me")

-----------

Why bother?  I (and many others, it seems) like the -i <#> option, allowing
for a ping interval.  Many ISPs like to hang up when there is a loss of
activity for a # of minutes on the line.  Using this allows a ping every #
seconds (500, for example) thus keeping the connection active.

ping -i 500 ibm.com

Hints
-----
I don't advise replacing the OS/2 ping.exe program with this one, although you
can if you want.  Some applications (WBI, for example) seem to rely on the
OS/2 ping and its syntax during installation.  I have renamed mine to
'uping.exe' and put it in my path.

Changes
-------
This is simply the first FreeBSD ping.c I could find on the net, and
recompiled for OS/2 with EMX 09c. It isn't optimized in any way since the
following is returned when optimized, and I don't have the patience to figure
it out. :)

\emx\lib\sigbsd.obj(sigbsd.obj) :  error L2029: '_uflags' : unresolved external

I made 2 small changes for my own use.  I'm only releasing this since no one
else seems to want to.

   - Return codes (error levels) are based on the % of pings that fail to
     be returned.
     - return code 0 means no pings failed, and the connection is good
     - 0 < return code < 100 means that the connection is 'iffy'
     - return code 100 means all pings failed, and connection can't be made
   - -h was added to hide the header, making a cleaner view in rexx scripts
     that want to ping and handle return codes, but not display any of the
     ping program.


Example REXX Script
-------------------
If you have friends/colleagues with static IP addresses, and want to know if
they are connected while you are, here is a simple script to run. Edit the
'hosts' array and add as many hosts as you want, starting at 1.
- sample.cmd is included.
