20X2, SETFREQ m64 and Terminal at 76800 baud

[MartinM57]

#picaxe 20x2
#no_data
#no_table
#terminal 76800
setfreq m64
do
    pause 100
    sertxd ("U")
loop

..produces no output in the Terminal window, but perfect output into Bray's Terminal. Works fine in both with:

#picaxe 20x2
#no_data
#no_table
#terminal 38400
setfreq m32
do
    pause 100
    sertxd ("U")
loop

Ideas please?

I've found that sertxd doesn't work at m64 - i've just learnt to go down to m32 for sertxd-ing.

I hadn't tried any other terminal, so assumed it was a hardware problem. I'll try with a different terminal next time I'm using a 20X2.

Bray's Terminal and my scope have no trouble decoding sertxd at 76800 - looks like a problem in the Terminal window...

This appears to be an issue with the Terminal rather than the PICAXE. We'll look into that.

Note that 76800 isn't a standard PC-supported baud rate so operation dependends on OS, type of interface and device drivers. The AXE027 has worked successfully at 76800 baud on all Windows OS's I've tried.

A minor patch is now available to correct this 5.2.10 issue on the software download pages.

@Technical,

I believe that this should also be mentioned in the New Product Releases forum.

@Technical,

One presumes that an update to PICAXE Manual 2 covering the X2 parts to a better extent, and including from the above query the #Terminal and the SERTXD commands might also be forthcoming.

What happens if you change it to serout?

@RogerTango : Just to note you're responding to a year old thread. Later Programming Editors handled 76800 baud, SERTXD and SEROUT.
