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
- 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.
