Re: How to prevent line wrapping of hex data?

I knew there was a way to do this, but I couldn't remember the details.
After some searching I found that 5.2 has an "snmp.conf" directive
"hexOutputLength" which you can use to set where to break the line.
Setting it to 0 will have it print everything on one line.

It doesn't look like the docs were updated when it was added, but the
feature is there. I'll update the man page for the next release.
