Hello I am in win 10pro, I use prolific usb to send morse via n1mm plus sofware, prolific was installed but it does not work very well, morse sound with a problem of weight, dit and dat sound with a timing problem, It is like a DTR and RTS delay problem.BTW it works fine in a old N1mm.N1MM team say.N1MM+ uses.Net and different Microsoft serial port support code than N1MM did. Some Prolific drivers introduce latency with the MS serial port code used in.Net but do not with MSCOMM32.OCX which the old version used. Windows 10 Ati Graphics Driver. This is a deficiency in the *Prolific driver*, not in our code. Any idea to resolve this puzzle.
