20D with Firewire?

[Doom1701e]

I was reading the specs on the 20D at B&H's website and saw this excerpt:

Remote Control RS-80N3 Remote Switch
TC-80N3 Timer Remote Controller
LC-4 Wireless Controller
Can also be controlled by computer when tethered
via IEEE1394 (FireWire) interface

Is this true or just a misprint?

No mention of Firewire on Canon's website, nor on reviewers' sites...
