[comp.sys.ibm.pc.hardware] MNP 5 and V.42 communications problem...

Hello again netlanders.  I have an MNP 2-5, V.42 modem running with a
2400 baud data pump and I can't figure it out.  If I run it as a regular
2400 baud modem, it works beautifully.  But when I get an MNP connection,
(MNP 4 error correction is all I have been able to find supported) the modem 
slows down to what seems like baout 10 baud!  I have turned cts/rts flow 
control on and xon/xoff flow control off.  The transmit error light is not
coming on so I know it's not resending the packets.  How can I fix this?  I
would really like to use the MNP features of the modem.  Is there a possibility
that my cable doesn't really support cts/rts flow control?  How can I check?
I am running on an XT clone.  Once again, thanks...
