Anything with an FTDI chip.

Note however, you will need to use EXTFSK with MMTTY or "Software
Generated FSK" in RTTYrite.  The accuracy of software generated FSK
will be dependent on the speed of your CPU, the number and nature of
the other USB devices connected to the computer, and the number of
other processes running on the system.

If you are concerned for accurately timed RTTY and the ability to
operate both 45 and 75 baud RTTY, look for and Edgeport USB to serial
device or one of the CAT/soundcard/RTTY interfaces that implements a
*true UART* like the microHAM "keyer" products.  Both the Edgeport
and microHAM "Keyer" products generate the bit timing in the UART
(not the computer CPU) and provide much less jitter by eliminating
the multiple sources of potentially significant timing errors that
occur in the CPU and USB systems.
