[TriLUG] TTL Serial port cable

[Brian Phelps]

Better get out your 32awg wire, spectacles, and soldring iron though to
make the mod, being that its SMD. 

On mine:
$ lsusb 
Bus 005 Device 001: ID 0000:0000  
Bus 004 Device 001: ID 0000:0000  
Bus 003 Device 008: ID 0403:6001 Future Technology Devices
International, Ltd 8-bit FIFO


Most FT-based use this chip which has an 8-bit fifo for CTS,RTS etc
lines.  See this for more info:
