Hi Robert,

I just followed your example above from our Compaq OSF/1 5.1 machine:

DATALOC ADD PUB gp16.wwb.noaa.gov
DSINFO I PUB

<nothing/hung>

I then tested to see if the ADDE ports were open:

telnet gp16.wwb.noaa.gov 500
<ok>

telnet gp16.wwb.noaa.gov 503
<nothing>

So, uncompressed transfers are evidently OK.  I tested this by changing
my compress/uncompress setting on McIDAS startup (I handle this through
my GUI startup; the user does not have to set a Unix environment variable!)
and DSINFO now works fine:

DSINFO I PUB

        Dataset Names of Type: IMAGE in Group: PUB

Name         NumPos   Content
------------ ------   --------------------------------------
BREF         99999
BREF2        99999
GCSHEM04I2      10
GEFDSK01V        8
GEFDSK04I2       8
 ...

So, it looks like someone in charge of the machine should be contacted
and asked to allow ADDE transfers through port 503.

Later...

Thanks, actually I found an e-mail from Brian in my Universal box that
I had missed before that said I should turn MCCOMPRESS off..I never saw
the e-mail.

I have e-mailed him and he has put in a request to turn 503/compression
on.
