mwavem - Mwave/ACP modem support daemon
mwavem [ <conffile> ]
mwavem 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 and 770.
mwavem 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.
<conffile> is the mwavem configuration file. The default is
/etc/mwavem.conf. (In Debian, the configuration file is
/etc/mwavem.conf the configuration file
/dev/mwave 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.
