This tool sends an ARP request using the packet driver API, waits for a
reply, and then displays the result. Its primary purpose is to verify
basic connectivity between your PC and other hosts on the local network.

Usage: ARPCHK <YOUR_IP> <TARGET_IP>

Example: ARPCHK 10.0.0.55 10.0.0.1

arpchk requires no TCP/IP configuration. It obtains its own MAC address
directly from the packet driver and only needs to know which IP address
you want to use as the source. You may specify any source IP as long as
it belongs to your LAN and is not already in use by another device.
