Connect two computers via USB
EETimes.com reports that FTDI Ltd., a company in Scotland, has “has developed a 2.5 meter USB-to-USB null modem cable (NMC) suitable for connecting to [sic] PCs together.”
Null-modem was developed to allow two DTEs to communicate through an RS-232 serial cable. The USB cable developed by FTDI has USB type A plugs at each end which contain a FT232RQ USB-UART converter IC and supporting components. The rate of communication between PCs is up to 3-Mbaud and the drivers work on Windows, Linux and Mac OS.
One of my first questions to myself when I started learning about USB was “Why can’t we just run a USB cable between computers to connect them?” It seems FTDI has answered that question and solved the problem. Though, with the popularity and speed of ethernet connections nowadays, I’m not sure why they would want to research null-modem USB cables.
