Both USB II and USB III have a separate driver connected 
to the DTR line that can be used with MMTTY/EXTFSK or 
"Software FSK (DTR)" in Writelog.  DTR is the same line 
as used for CW but the separate drivers allow both to be 
connected at the same time. 

If one is looking for a UART ("COM port") interface, that 
is only available in the "Keyer" line (DigiKeyer, microKEYER, 
microKEYER II and MK2R/MK2R+).
