Try adding the settings:

        --
        lcp-restart 1
        ipcp-restart 1
        --

Also.. what serial port are you running at 230400?  A 16650? 
Maybe a Hayes ESP card?  Also, what kernel are you running?  
A 2.1.x/2.2.x kernel I hope.  

If you are running a 2.0.x kernel, a 16650 will NOT work.
Per 2.0.36 in /usr/src/linux/drivers/char/serial.c at line 
1244:

--
/*
* On the 16650, we disable the FIFOs altogether
* because of a design bug in how the implement
* things.  We could support it by completely changing
* how we handle the interrupt driver, but not today....
*
* N.B.  Because there's no way to set a FIFO trigger
* at 1 char, we'd probably disable at speed below
* 2400 baud anyway...
*/

If you are running a 2.0.x kernel, setting the speed in the
options file to 230400 is wrong.  The 2.0.x kernels, you'd 
need to set the speed in two places.  For example, to set 
/dev/ttyS3 to 115200, you would configure the serial port 
in /etc/rc.d/rc.serial to use the setserial tool with
spd_vhi.  Then, in the options file, you would use the port
at 38400.  With these two options, you would get 115200 at the
serial port.  Lame huh?  They fixed this in 2.1.x and 2.2.x.

I would also bump the MTU and MRU to 1500 just for now.
