[comp.sys.ibm.pc] PIBTERM v4.0.6 - can't send nulls

        I  recently  got  the  latest  release  of PIBTERM (4.0.6)  from
        SIMTEL20.   I can't get it to send out nulls  (ASCII  0).    The
        previous  version of PIBTERM that I was using (4.0.2) would send
        nulls  fine by using ^@ (CTRL-@).  Now when I press ^@,  nothing
        happens;   the transmit data LED on my modem doesn't even flash.
        I need to  be  able  to  send  out nulls for the LISP editor I'm
        using.  Can anyone  tell me why null transmission capability has
        been disabled in PIBTERM 4.0.6?  By the way, I'm using the VT100
        emulation mode.
