TI Graphlink Linux Software?

ajalics asks: "I need a program to transfer files between my Linux box and my TI-86. TheTI family of graphing calculators use an 1/8" jack to a serial port called a TI graph-link. Unfortunatley TI only provides Windows, Mac, and DOS software. Does anyone know of any Linux software that will let me talk to my TI?" If no software exists at this point, is someone working on reverse engineering the protocol?
