Re: [gpsd-dev] tests hanging on netsbd-6 i386

It looks like 301 is ok and 302 is hanging.

-rw-r--r--  1 gdt  ir    13249 Jan 30 10:57 CHECK.release-3.11-301-ga83ecfd
-rw-r--r--  1 gdt  ir     4774 Jan 30 10:53 CHECK.release-3.11-302-g646f855

Also, 301 prints out

gpsd:SHOUT: tty params optimized for min length 16 of textual packets

and 302 does not.


Are raw tty devices on linux always non-blocking?  I can see how code
that does

   select
   if (readble(fd)
      read a byte from fd

would work ok with either nonblocking io or not, but if the device isn't
set in nonblocking mode then

   select
   if (readble(fd)
      read 16 bytes from fd

should just pend in the read.
