L.sys & BREAK. HELP??

[Mark Turner]

I seek to communicate via uucico with a system (call it "system") that
answers at 9600 baud, but which can be made to toggle to 4800baud by
sending three breaks from a terminal.  I cannot make uucico on my
system imitate the sending of those three breaks.  My system (an LMC system
2 running 4.1 Genix) does not seem to understand the \b \d \r notation.
But it does claim to understand BREAK.  I have crafted an L.sys entry
that should send several breaks, with many carriage returns in between.
Nonetheless, that string of breaks will not make the remote system
toggle to 4800baud.  Here is the L.sys entry, with names and
numbers changed to protect the innocent:

system Any tty02 4800 tty02 > D > [phone-number] TED 111 x 111 "" 111 "" 111 "" 
BREAK x 111 "" 111 "" 111 "" 111 "" BREAK x 111 "" 111 "" 111 "" 111 "" BREAK x 
111 "" 111 "" 111 "" 111 "" BREAK x 111 "" 111 "" 111 "" 111 "" BREAK ogin: ??? 


The first part of this entry is directed at an IBX dialer, which expects
a D and a phone-number in succession, after which it responds 
DATA CALL INITIATED.  From that point on, my system is trying to make
the remote system toggle to 4800b.

Here is the command to call:
/usr/lib/uucp/uucico -r1 -ssystem -x9

Here is uucico's yack:

gdial called
finds called
getto called
call: no. tty02 for sys system Speed: want 4800 use 14 ps 4
login called
wanted > _ENTER_-_DIRECTORY(D),_NETWORK(N),_OR_OUTSIDE(O)_>got that
wanted > _D____ENTER_DESTINATION_NUMBER_>got that
wanted TED _[phone-number]_DATA_CALL_INITIATEDgot that

* at this point, the phone call has been put through, and my
* system is trying to make the remote system toggle.  It continues . . .

As you can see, sending all these breaks, with carriage returns interjected,
never makes the system toggle to 4800baud.  HELP?
