10.27.2Description
Sends an ICMP Echo message to the specified IP address.
•
can be obtained by repeating the ping. command with increasing TTL values,
starting with 1.
•
IP header (20 bytes) and the ICMP header (8 bytes).
ATMOS TCP/IP waits 10 seconds for a reply to the message; if none arrives, it
reports the lack of a reply (and returns the TELL message, or redisplays the prompt).
Any reply arriving after this time-out will be reported as a background message.
(Whereas a reply arriving before the time-out expires is, of course, reported in the
foreground.)
A reply is an ICMP Echo Reply message, or an ICMP error message reporting
destination unreachable, time exceeded, or (as should never happen) a parameter
problem. ICMP redirect and source quench messages are reported, but ATMOS
TCP/IP continues to wait for a final reply or time-out.
