The single biggest difference between the TI GRAPH-LINK and any other link
cable (homebuilt or otherwise) is that only the GRAPH-LINK actually
converts standard, 9600 bps RS-232 to TI's custom protocol (and vice
versa). All the other cables rely on PC software to control the lines of
the serial port directly to emulate TI's protocol. That's why only the
GRAPH-LINK is usable on a mac.
