[En-Nut-Discussion] Ping

[Ralf Spettel]

Hello Ralph,
where can I find the 'NutIcmpReply' with seven parameters, which is called 
from your 'NutIcmpSendTo' in the sample below ?
The original 'NutIcmpReply' has only five parameters..

The 'NutIcmpSendTo'  was found at http://www.ethernut.de/arc/rm-icmp.zip
