Hi guys,
as far as you know are there any limitations on serial port speed on a
gumstix basix 400xm-bt?

Thanks,

Hi Guiliano

I believe the different ports actually have different limits. From memory
the HWUART can go the fastest (1Mb maybe), the others are probably limited
to 115200 or 230400.

others will chime in with more accurate figures. But I'm sure its all
available from the wiki (www.gumstix.net and choose support).
