INFORMATION - What this test is all about

T_REMOTE tests the asynchronous remote file system implementation, introduced in
F32 release 110 and refined in release 112.  The test sets up and mounts four drives,
the default drive (usually C on WINS and MARM), a remote drive (Q) and two others, on
MARM these are C and D, on WINS these are X and Y.  The remote filesystem is the only
system treated asynchronously by F32.  

The test sets up a thread for each drive and runs a number of tests on each drive.
In the remote filesystem case, a dummy filesystem has been implemented, this is built
as T_REMFSY.fsy.  The tests are designed to stress a number of fileserver API
functions.  The test MultipleSessions() is adapted from another F32 test T_SESSION.
It sets up an array of fileserver connections and then uses each connection to run
a number of tests - alternating between connections to stress F32 as it does so.  The
test should therefore be testing multiple fileserver connections on multiple drives -
the remote filesystem running concurrently with the other drives.  There should be
no failure or confusion between fileserver sessions.  Each drive has a separate test
console which should complete successfully.

NOTE: TO RUN THIS CARD SUCCESSFULLY ON MARM A CF CARD IS REQUIRED
