There is even more frustration sometimes than hte communication with the
driver, as related by Jacques=2E  For some AMR hardware, the ltmodem DSP
drivers do support communication with the modem, as in the case of Eugene'=

 What Eugene (and he is not alone) seems not to know is that a modem
driver can always be loaded in memory just as any other program, and the
keyboard and display can talk with the software just loaded, thus many
AT=2E=2E commands work, because they talk with the driver software only, n=
ot
with the chipset=2E
 But when it comes to ATD (dial), of course, it will never work, because
the hardware (chipset) is only correctly operated by the driver software
written for that specific chipset, which, as Marv writes, does not (yet)
exist in the present case=2E The driver sends your ATD=2E=2E commands "in =
the
air", to nothing existing, waits for the DIAL TONE which will never come
because no signal was created on the phone line nor detected, and gives up=

after some time=2E
