I have to say I love using ZOC as well.
The download problem stems from the fact that ZOC seems to require a lot
of CPU cycles when downloading or uploading. I use MEMSTAT to monitor
my system. The modem I use is 2400. When I use something like LiveWire
to download and I have a few small background tasks going like a clock and
CD player and a few small games, the CPU% is about 24% to 30%.
This is on a 386DX-40. If I open a couple of OS/2 windows and do a few other
things this jumps to 90% to 100% depending on what I am doing.
I even run a digitized music player DMPlayer .99 at 22000khz and in stereo
with no problems.
When I download with ZOC in the same set up at 2400, even opening an
OS/2 command line window give errors.
For some reason ZOC is a CPU hog when downloading, no matter what rate it
is receiving at, even 2400. MEMSTAT reports about 90% cpu usage.
Either ZOC is doing something clever or there is a bug.

Keep in contact.
