[WT-support] CW Speed variations

[f6ify]

Hi,

   I am the happy owner of a MK2R+ and, as José, I use the CW generated 
by Win-test via virtual com-port to avoid this annoying problem of speed 
variation. USB seems not a problem, FSK from MMTTY/Win-test via same 
interface works also without a glitch.
