20040723: 20040722: 20040722: IP -10 error for



Jon,

I have tracked down the source of your trouble reported below.
It seems that over time, bytes 21-24 have changed from 4 space 
characters to 4 null bytes. The current code is only checking for 
the 4 null characters, and otherwise is expecting a station ID. 
I have modified the code for a release of 5.7.3 to handle the old
format.

In the mean time, I have placed a preview release tarfile of a 5.7.3
linux binary on our download server if that fits your needs. This
allows gpnexr2 and nexr2rhi to display the data. Not all documentation in
the tarfile has been updated, so the final tarfile will differ.
