p<USER>,<PASS>~
This is the default Iridium dial script used to connect to a normal ISP. <DIAL> is the full
(international) dial-in number of the provider and <USER> and <PASS> are the account’s
user name and password respectively.

user name and password respectively.

5.17.8.2 Setting the destination addresses and ports
The destination addresses and ports can be entered from the TCP/IP menu. The menu is invoked
by the “settcp” console command. The destination addresses and ports tell the buoy where the
iBuoy software is running. In other words, they contain the internet addresses of the computer
where the data must be send to. The addresses consist of two parts, the address itself and the
port number. The address itself may be either a straight IP address (for example 81.4.80.140) or
a domain host name (for example www.datawell.nl). The buoy differentiates between the two
by looking at the first character of the address. If it is a number, the address is assumed to be a
straight IP address, otherwise it is assumed to be a domain host name. The domain host name is
resolved by a built-in DNS client. The address must be less than 32 characters long. Valid port
numbers are between 0 and 65535. The exact port number is determined by the iBuoy
configuration on the destination computer. Please refer to the iBuoy manual for more
information. There are two address/port settings; addr1/port1 and addr2/port2. Addr1/port1 is
the primary destination; addr2/port2 is the secondary backup destination.
5.17.8.3 Setting the session interval
The session interval is entered from the TCP/IP menu. The menu is invoked by the "settcp"
console command. The transmission interval specifies how often the buoy will attempt to make
contact with the destination host. The session interval is specified in half-hour increments with a
valid range of 1-48. For example, to let the buoy dial in 4 times per day (24hrs) you would enter
(24hrs/4=6hrs) 12. To let the buoy dial in every half-hour (minimum transmission interval) you
would enter 1. Additionally the buoy will also attempt to make contact around midnight,
independent of the entered session interval. The session intervals are "aligned" to the buoys
internal half-hour measurement cycles. A session may therefore seem "late" or "early"
compared to the local or UTC time. This is normal behaviour.
NOTE: To save airtime costs due to endless retries, the session interval may be temporarily
overruled and set to '24' by the buoy. This happens when the destination computer has been
turned off. The session interval is restored again once the destination computer is switched back
on.
5.17.8.4 Setting the buoy identification string
The buoy identification string is entered from the TCP/IP menu. The menu is invoked by the
“settcp” console command. The buoy identification string is used to let the buoy identify itself
to iBuoy. When multiple buoys are being used, the identification string is useful for discerning
between the different buoys. The buoy identification string can be any text chosen by the user
and must be less than 32 characters long.
