By default, the TI-84 Plus uses the USB port if it is connected. If the USB cable is not
connected, it uses the I/O port. If you want to specify either the USB or I/O port, use the
following portflag numbers:
portflag =0 use USB port if connected;
portflag =1 use USB port;
portflag =2 use I/O port
Note: GetCalc( does not work between TI .82 and TI-83 Plus or a TI.82 and TI-84 Plus
calculators.
Get(, Send( Get(, Send( Get(, Send( Get(, Send(
Get( gets data from the CBL 2™ or CBR™ and stores it to variable on the receiving TI-84
Plus. variable can be a real number, list element, list name, matrix element, matrix name,
string, Y= variable, graph database, or picture.
Get(variable)
Note: If you transfer a program that references the Get( command to the TI-84 Plus from
a TI .82, the TI-84 Plus will interpret it as the Get( described above. Use GetCalc( to get
data from another TI-84 Plus.
Send( sends the contents of variable to the CBL 2™ or CBR™. You cannot use it to send
to another TI-84 Plus. variable can be a real number, list element, list name, matrix
element, matrix name, string, Y= variable, graph database, or picture. variable can be a
list of elements.
