If the CNI2 detects a decimal point (.) or a forward slash (/) in the dial string it will assume
this is an IP address and Port #, and not a standard phone number.

+++ (escape) Command

Once the CNI2 has established a connection with the central computer it can no longer respond
to AT commands. However AT modems are always looking for an "escape" sequence, which is
"+++" preceded and followed by 1 second of quiet time. This will return the CNI2 to command
mode and the unit will respond with an "OK" message.
Following this the CNI2 will wait 5 seconds to receive an "ATH" (hangup) command from the
device. If the command is received, or 5 seconds elapse, the CNI2 will terminate the
connection with the central computer and will return a "NO CARRIER" message to the remote
device.

AT Command Chaining

"AT" commands can be grouped together into one string. For example, the command "ATE0V1"
commands the CNI2 to turn off echoing and return verbose responses. However "ATA", "ATH"
or "ATD" commands should be sent separately or should be the last command in a chain.

AT+ICLK? (time and date) Command

This command is only supported when the CNI2 is configured as an InvisiConnect
This command will return the present time and data information to the serial device.
InvisiConnect provides the time to the CNI with every call if that feature has been enabled.
If the CNI does not have a valid time, or if it is in need of an updated time from InvisiConnect
an "ERROR" message will be returned to the remote device. Otherwise the response will be
formatted as follows, including delimiters such as quotation marks ("), forward slash (/) and
colon (:):
<cr><lf>+ICLK: "yy/MM/dd,hh:mm:ss±zz"<cr><lf>
where:
yy = 2-digit year [00-99], as in 2000-2099]
MM = 2-digit month [01-12]
dd = 2-digit day of month [00-31]
hh = 2-digit hour [00-23]
mm = 2-digit minute [00-59]
ss = 2-digit seconds [00-59]
± = "+" or "-"
zz = time zone offset from GMT in ¼ hour increments [-48 to +48]
The time represents the time on the InvisiConnect
zone then the "zz" offset can be used to calculate a correct local time.
