[WriteLog] Erratic CW using FTDI USB serial port

Hi,
Some of those plug in cards with a serial port use an FTDI USB to serial conversion chip.  They have the same problem as a cabled converter.  Been there, done that, still got the useless card laying around here some place.

Take pride in the USA. 73

Just a thought, Darren.  

Does your laptop accept any plug-in cards?  (e.g. PCMCIA?)  If so, you could purchase one inexpensively online.  These give you one or more "native" serial ports.

It's not RF as i'm only keying the side tone, it's not the interface as it works fine with Logger32, SD and N1MM, but I'm hoping there is a simple line to add into the writelog.ini file to make it behave itself?

But I've now changed the 'holiday laptop' to a newer one and it doesnt have a com port. I was hoping that the erratic behaviour was machine specific but its still the same on the newer laptop. If I can't solve this I'll have to go down the separate USB serial port route as I'm really reluctant to buy another winkey USB. In these times of extortionate excess baggage charges every LB/1/2 KG helps and the fewer cables/interfaces I need to pack the better it is.
