Hello, I've been running ldm 5.0.9 forever on a Sun Ultra 10 with the
NOAA Weather Wire service feeding serial port b.  This has worked fine
for several years.

I've tried a few times to upgrade from ldm 5 to 6.0.X and seem to have a
problem with the data being identified as it comes in.

The LDM 5 ldmd.conf (works fine with 5):

exec    "pqbinstats"
exec    "pqact -v"
exec    "afos -v -b 9600 -p none /dev/ttyb"


When I switch to ldm 6.0.14, I notice in the logs:

Feb 18 18:16:38 weatherman rpc.ldmd[24106]: Starting Up (version: 6.0.14;

however "ldmadmin watch" shows nothing actually getting into the queue.
even though the buffer size keeps growing

I modified ldmd.conf (for 6.0.14) to:

exec    "pqbinstats"
exec    "pqact -v -l /tmp/pqactlog"
exec    "afos -r /tmp/rawdata -v -b 9600 -p none /dev/ttyb"


contents of /tmp/pqactlog:

Feb 18 18:21:46 pqact[24219]: Starting Up
Feb 18 18:21:46 pqact[24219]: Successfully read pattern file

And the rawfile is filling up with text, so the data is coming in.

Here's the first product:

Is there anything that changes significantly in ldm 6 that would cause
this behavior?  Any help is greatly appreciated!

Thanks-

David
