Not to late to mention a new device, EZMaster, that use USB port, that
combined with the right software can be overcome all the SO2R problem even
CW/SSB/RTTY.

The problem is the need to "read" the serial data stream and catch
the proper VFO commands. That requires a UART in, some intelligence
(PIC or more advanced microprocessor), a UART out and a parallel
driver.

Not to my knowledge ... I know of one vendor working on a standard
for serial control using USB virtual ports and custom hardware.
Unfortunately, this will take a serial port of the "opposite" sense
of the normal PC port. The PC port (DTE) has only two controllable
output lines: DTR and RTS ... while the opposite port (DCE) has four
controllable outputs: DSR, CTS, CD, and RI.

Not to my knowledge.
