[9fans] discrepency between plan9 and ixpc

[Eli Cohen]

hello everyone, i have been working on a 9P arduino library. it works now
with ixpc from libixp, modified slightly to communicate over the serial

ixpc ls /

arductl
ardudata

however, i am getting this on plan9:

% echo b115200 > /dev/eiaU0/eiaUctl
% mount -ncC /dev/eiaU0/eiaU /n/anything
% ls /n/anything
anything

the output of ls is just whatever directory i mount it in, though accessing
arductl and ardudata works fine despite their absence from the directory
listing.

anyone have any ideas what i might be doing wrong?

the source code is at https://github.com/echoline/NinePea

ps.
and sorry for calling you a grinch

Without looking at the code it sounds like
you're not getting the Rstat correct. Does
the root qid return "/" for the stat name?

You can use iostats(4) to help investigate.

Cheers,
