The FT245B/R devices interface to a parallel 8 bit data buss. Same function as 
the FT232. The FT245B is $6.33 in unit cost and the FT245R is $4.94 unit cost. 
Like the Cypress SH811 device, someone has to write drivers for DEB/OS9 to 
make them useable. From best I can tell the FT245 would be a better solution 
than the Cypress chip due to errata and the lack of Cypress to correct some 
issues in the chip design.
