NetPlex/!Netplex/SocketFS/Faq
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

Q1. What happens to OOB data.
A1. Unless you're specificaly watching event 19 yourself, little.
I do not look for or do any special handling for OOB data.
Q2. BGET#X% never returns.
A2. BGET#X% only returns if there's data waiting to be sent. On Freenet
you can see if there any data waiting by doing *netstat and if the
Recv-Q entry for the socket you're interested is non-zero, there is
data waiting. Otherwise BGET will wait for data from the remote side,
while it is waiting you won't be able to do anything else with
socketfs on this socket. As the calls are blocked by risc-os, so
if you need to prod the remote machine to get the data, prod it before
you run BGET.
