<< OPERATIONS AND SIGNALS
----------------------
On UNIX, sending a TERM or INT signal will cause the personal proxy to
shut down nicely, resaving all keyblocks that are still in memory to
disk, and closing all open network connections.
On UNIX, sending a HUP signal will cause the personal proxy to reload
its ini configuration file and reread most of the settings specified
within it.
On UNIX, sending an ALRM signal will trigger the personal proxy to
create an outgoing server connection. This is done even if your
connectivity mode is set to offline. This behavior is intentional, and
permits clever scripters to automate periodic dialups and forced server
flushes.
On Win95/98/NT, when running the proxy in a window you can press
Ctrl-Break at any time to perform the equivalent of a HUP+ALRM signal on
UNIX. To actually close the proxy, press Ctrl-C or close window.
On OS/2 you can press Ctrl-C to force a reload of the ini file and
create an outgoing server connection. Ctrl-Break is used to close
the proxy. >>
The bold paragraph is your problem. With WinNT/2K, and the PProxy as a service, that option is only available to UNIX.
