WIndows XP cannot dedicate an I/O port with no interrupts and will continue 
time slicing all serial, parallel, and usb I/O (even with no other programs 
running, due to internal interrupt calls)  Smooth CW is essentially impossible 
from software to I/O port due to the CPU constantly interrupting the CW stream 
to service interrupt calls...  It is not the fault of the logging program but 
an architecture constraint of the cpu...
  I am running N1MM currently and using it to drive an external keyer... I am 
using the Winkey2 USB keyer and have been happy with it...  But the other 
keyers should work also, Microham, etc...  What happens here is the logging 
program squirts an ascii sentence to the keyer... The keyer cpu then handles 
all the timing and keying chores without being interrupted by other tasks...  I 
suspect Wrotelog will work in a similar fashion with an external keyer...
