The delay when you are doing remote directories with NET: is because a full
512 byte fileheader is being transmitted for each file in the directory.
This means that for a directory with 100 files, at least 50K needs to be
transmitted across the serial link (about 4 minutes at 2400 baud). Of course,
this would be much faster if NET: simply asked for the filenames themselves
and not the full fileheader, but then it wouldn't be as compatible with
AmigaDOS.

At 2400 baud, NET: is a lot of fun to play with but don't expect to use it
for anything serious... (it's much quicker to open a remote CLI and type
DIR for example :-)

No ideas on your Dnet lockups I'm afraid.
