Okay, let's see what we got. I just commited the changes to MComInterface to
the SF CVS repository.

Basically, I added the following methods:
- Push() -> PLAYER_MCOM_PUSH_REQ
- Pop() -> PLAYER_MCOM_POP_REQ
- Read() -> PLAYER_MCOM_READ_REQ
- Clear() -> PLAYER_MCOM_CLEAR_REQ
- setCapacity() -> PLAYER_MCOM_SET_CAPACITY_REQ

While looking at test_mcom.cc, it seems that a proper test should look like:
- first subscribe to the interface using requestInterfaceMCom()
- use Push() to send some data (eg. Push (1, "test", data), where data is a
char array and "test" is the channel name)
- use Read() or Pop() (they look the same to me) to read data from a channel
(eg. Pop (1, "test"))
- check if the data has been read using isDataReady() and if true, use the
get* methods to get the desired data (getRData(), getDataType(), etc)

Unfortunately, I don't have any access to a Lifecom device, so I can't test
this properly.

If you have any troubles retreiving the code from CVS (use
http://sourceforge.net/cvs/?group_id=135304, Anonymous CVS Access section
for details) please let me know, and I'll build 1.6.3.2 and upload it
tomorrow.

Yours sincerely,
