@ SendCalc
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.

returns the results as a list. The original contents
of
