udhcpc problem

[Bin Chen]

        Hi,
        
        When the udhcpc is started, it begins to broadcast the DHCP
        discover
        message. Can I pass some arguments to udhcpc to let it just
        reside in
        memory but not do any action until I tell it to do using signal
        SIGUSR1
        or SIGUSR2?
        
        Thanks a lot.
        Bin
