File: comm.c

|
|
Desc: This file implements the actual transmission portion
|
||
|
|
of the "ok to power me down" message to the remote
|
||
|
|
power cycling black box.
|
||
|
|
|
||
|
|
It's been sepatated into a separate file so that
|
||
|
|
it may be replaced by any other comm mechanism desired.

(including none or non serial mode at all)
