Re: [OctDev] Alpha release of Serial I/O package (v0.1)

[Andrius S. <and...@gm...>]

Hey Juan,

So I upgraded VM to Ubuntu 10.10 and ran several tests with different
serial adapters and a virtual interface: pl2303 (
http://pastebin.com/0B2CdyYZ ), FT232RL ( http://pastebin.com/Wb4Yq1r6 )
and socat ( http://pastebin.com/uFCVtCgc ). Everything works as it should.

I can not reproduce the bug. I think the best for now would be to continue
the development and make a public release and see if anyone else has this
problem, as now there is a huge lack of testing feedback.

P.S. for socat I used: socat -d -d pty,raw,echo=0, pty,raw,echo=0

Best Regards,
