1. Press … and select 8:Link.
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 Laboratoryé (CBL 2é/CBL™) or a Calculator-Based
Ranger™ (CBRé), a program on the TI-89 / TI-92 Plus can
access the CBL 2/CBL or CBR.
