Hi Folks,

I've gotten Xlog to play nicely with my FT-450AT. But it seems as though
there's a sweet-spot in settings. Regardless of baud rate, if I sample
at 201 milliseconds, all is well. If I try a faster polling rate, the
program virtually freezes up. I'm currently set at 38400 baud, and while
all is well at 201 milliseconds, anything faster locks up the program.
Is there an extra setting I'm missing? Or might this be on the hardware
side of the river?

I notice that while the polling rate is 200 ms in the configuration
dialog, the *.cfg file in a text editor shows 201.
With best regards,


I would think 50ms would be a better setting, 200 seems quite high. One problem I ran into with my 450 was the CAT TOT setting. Default is set at 100ms, I raised mine to 1000ms and my CAT no longer timed out. That may be part of your problem here. Basically the CAT TOT puts the serial port to sleep with in-activity. I've never heard of such a thing, but I'm not a Yaesu engineer either. Mine works fine with 38400 baud rate.

I wouldn't worry about the 200/201.
