Here's what I (reproducably) do on my TP600E (2645-550):

 - make sure the loudspeaker is not switched off:
   (repeatedly hitting <Fn>-<PgUp>).

 - insert my PCMCIA modem (Venus K56FLEX V.90 kfav163 PCMCIA
   p52198) and run minicom using the default init:

    AT S7=45 S0=0 L1 V1 X4 &c1 E1 Q0

 - do a "ATA" command -> the PCMCIA modem produces the
   characteristic sounds.

 - Physically eject the PCMCIA modem (I guess this makes
   it pretty sure I'm not using it for the next steps :-)

 - Start up mwavem, setserial etc. (In fact, I also can perform
   this step before playing with the PCMCIA modem).

 - Start minicom on the ACP modem (again using what minicom
   defaults to: AT S7=45 S0=0 L1 V1 X4 &c1 E1 Q0

 - do a "ATA" command -> the ACP modem produces the anwering
   sound sequence (as a matter of fact, I can distinguish
   both modems because they produce quite different sounds)

 - I also can issue a "ATX3DT012345" (no connection to the
   phoneline, therefore the X3) and listen to the DTMF tones

 ---> On my machine, it works.
