10.27.2Description

Sends an ICMP Echo message to the specified IP address.
(default 30) is the TTL (time-to-live) to use. A crude traceroute functionality

can be obtained by repeating the ping. command with increasing TTL values,
starting with 1.

(default 56) is the data size of the Echo message. This does not include the

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.

Sets up a mapping between a UDP or TCP port and a symbolic name; deletes all
such mappings; lists the mappings; reads the mappings from a file; or displays help
