mwavem - Mwave/ACP modem support daemon
mwavem [ <conffile> ]
implements a Hayes-compatible V.90 modem in the International Business
Machines Corp. (IBM) 3780i Mwave Advanced Communications Processor
(Mwave/ACP) Digital Signal Processor (DSP) chip which is built in to
certain IBM ThinkPad laptop computers, including the ThinkPad 600, 600E
runs in user space, loading the DSP with instructions as required.
It must have adequate permission to access the mwave device node
associated with the mwave kernel device driver. The driver code
is included in the latest (as of January 2002) 2.4 Linux kernel
sources. To build the module, set "ACP/Mwave Modem support" under
"Character devices" to "m" at kernel configuration time. Source
code is available from IBM which can be used to build a module
compatible with earlier kernels.
is the mwavem configuration file.
The default is /etc/mwavem.conf.
(In Debian, the configuration file is /etc/mwavem/mwavem.conf.)
the configuration file
the mwave device
If you are using devfs then the mwave device driver creates
a device node at /dev/misc/mwave.
devfsd must therefore be configured so as to create a symbolic link
from /dev/mwave to /dev/misc/mwave.
If you are not using devfs then /dev/mwave must be a char device node
with major number 10, minor number 219.
Only the 3780i chip is supported. Earlier Mwave DSPs, which were used for
sound generation as well as modem functionality, are not supported.
