SendCalc CATALOG
SendCalc
var
Sends variable
var
to the link port, where another
unit linked to that port can receive the variable
value. The receiving unit must be on the Home
screen or must execute
GetCalc from a program.
If you send from a TI-89, TI-92 Plus, or
Voyage™ 200 to a TI-92, an error occurs if the
TI-92 executes
GetCalc from a program. In this
case, the sending unit must use
SendChat
instead.

var[,port
]
Sends contents of
var
from a TI-89 Titanium to
another TI-89 Titanium.
If the port is not specified, or
port = 0
is specified,
the TI-89 Titanium sends data using the USB port
if connected, if not, it will send using the I/O port.
If
port = 1
, the TI-89 Titanium sends data using
the USB port only.
If
port = 2
, the TI-89 Titanium sends data using
the I/O port only.
SendChat CATALOG
SendChat
var
A general alternative to SendCalc, this is useful
if the receiving unit is a TI-92 (or for a generic
"chat" program that allows either a TI-92,
Voyage™ 200, or TI-92 Plus to be used). Refer to
SendCalc for more information.
SendChat sends a variable only if that variable is
compatible with the TI-92, which is typically true
in "chat" programs. However,
SendChat will
not send an archived variable, a TI-89 graph data
base, etc.
