2. Select a command.
When two TI -89 / TI-92 Plus calculators are linked, one acts as a
receiving unit and the other as a sending unit.
Command Description
GetCalc Executed on the receiving unit. Sets up the unit to
receive a variable via the I/O port.
¦ After the receiving unit executes GetCalc , the
sending unit must execute SendCalc .
¦ After the sending unit executes SendCalc , the
sent variable is stored on the receiving unit (in
the variable name specified by
GetCalc ).
SendCalc Executed on the sending unit. Sends a variable to
the receiving unit via the I/O port.
¦ Before the sending unit executes SendCalc , the
receiving unit must execute GetCalc .
SendChat Executed on the sending unit as a general
alternative to
SendCalc . Useful if the receiving unit
is a TI -92 (or for a generic "chat" program that
allows either a TI -92 or TI -92 Plus to be used).
For additional information, refer to the manual that comes with the
CBL 2/CBL
or CBR unit.
Command Description
Get Gets a variable from an attached CBL 2/CBL or CBR
and stores it in the TI -89 / TI-92 Plus .
Send Sends a list variable from the TI -89 / TI-92 Plus to the
CBL 2/CBL or CBR .

If you link two TI - 89 / TI - 92 Plus calculators (described in
Chapter 22), programs on both units can transmit variables
between them. If you link a
TI - 89 / TI - 92 Plus to a Calculator-
Based Laboratory é (CBL 2 é /CBL™) or a Calculator-Based
Ranger™ (CBR é ), a program on the TI - 89 / TI - 92 Plus can
access the CBL 2/CBL or CBR.

that synchronizes the
receiving and sending units
so that GetCalc and
SendCalc
are executed in
the proper sequence, refer
