[WP-34S] Cable and flashing options for Mac users

[dewster]

I recommend you move this to a PC. The WP-34S programming process is opaque enough - add yet one more unknown to the chain and you will likely go insane.

Serial ports are a shaky way to do this kind of thing, no flow control, no error correction, just a data blast with a checksum or CRC or something at the very end that - if you are lucky - lets you know if you blew it. When it works it works, but god help you if something goes wrong.
