I had a similar requirement to be able to knock Binkley offline long enough for 
a maintenance routine to trim its logs.  Because my processes were scattered 
between the DOS mailer node and and OS/2 node across a Netware LAN, the 
solution required a combination of Binkley's flag file support (which can be 
used to force Bink to exit with a specified errorlevel) and a semaphore file 
written to the server.  The logic flows something like:

Log process creates flag file to force Bink to exit and then loops, waiting for 
the appearance of a semaphore from the Bink process to acknowledge that it 
indeed has exited.  Binkley process finishes doing whatever work it might have 
been doing when the flag was created, detects the flag, exits with specified 
errorlevel, and branches to BAT/CMD logic that creates the semaphore and loops 
while that semaphore exists.  Log process exits wait-for-semaphore loop, does 
its work, and then deletes semaphore. Binkley exits wait-while-semaphore loop 
and recycles.

Sounds convoluted, but it really only involves an additional 6 or 8 lines 
scattered across the two batch jobs to implement.  You'll spend more time in 
the Bink docs figuring out exactly how that damn flag file has to be named to 
match your Bink implementation.  For mine, it is something like BTEXITxx.yy: 
where xx is the task number (node) in hex and yy is the errorlevel in hex...but 
this may vary between versions or in XE releases, so check your dox (including 
WHATSNEW) before you start.
