5.2.2.10. FORceclose command:
Force close command closes all TCP/IP ports. New sessions can be
established immediately.
example:
• FORceclose (closes all open TCP/IP ports)
From the front panel keypad, this command can be executed
using STOre 224. Also, an exclamation point ("!") followed by a
linefeed (Ctrl-J if your Telnet program is not set up to automatically
send it) on the Telnet port (23) can be used to force close the
ports.
Background: Unlike web sites that must allow thousands (or
sometimes millions) of simultaneous connections to a "port", the
CPU allows only one connection to each port.
When the host is done with its session, it tells the other device so
that it can close its port and make it available to another session.
In certain conditions, it's possible for the host to close its session
without the device finding out. (Examples: an Ethernet hub or
cable is disconnected in mid-session and the host terminates its
session.) In these conditions, the FORceclose command can be
used to make the port available again.
Additionally, the inactivity timeout may be used to automatically
close the port if no activity is detected after a user defined
amount of time. See GET?/SET value 25 in Section 5.2.3 for more
details.
5.2.2.11. RESet command
This command performs a system reset.
RESet
Performs a system reset. If SET 30, 0 was performed prior, the system
resets with factory defaults, otherwise, it performs a "normal" reset.
If Autorestore is TRUE (Set/Get? 22), the connections are restored.
