+       Say "Y" to use a character device for the External Shared
+       Memory (XSHM) IPC mechanism. XSHM is an IPC protocol used to
+       talk to external device such as modem over a shared memory
+       (e.g. Chip to Chip).
+       Only say "M" here if you want to test XSHM and need to load
+       and unload its module.
+       If unsure say N.
