Mike,
    This is the way I have it setup with SPITFIRE.

    <S> Serial Port No......................: 2
    <B> System Baud Rate....................: 57600
    <I> Initialitaion String................:
        AT&FE1V1X4&C1&D2S0=0S7=3095=44W2
    <M> Modem - Error Correction Type.......: Yes     <1> Line COM1.. : IRQ3
    <E> Error Correction Message............: ARQ     <2> Line COM2.. : IRQ3
    <H> Hardware Data Flow Control..........: Yes     <3> Line COM3.. : IRQ4
    <A> Answer On What Ring.................: 1       <4> Line COM4.. : IRQ3
    <D> Display Result Messages.............: On
    <C> Disconnect Delay....................: 30
    <U> Use High Speed Async Routines.......: Yes
    <R> Baud Rate Requirement...............: 0
    <L> Break Length..(1000=1 Second).......: 0

    Try this and see how it works.  Make sure you start at the top at
    <S> and work your way down as you set it up.
