-Device driver operation may be tested from command line for some functions, for example:
-
-{{{
-# echo “A,B,C” > /dev/cardbeep <CR>
-}}}
-Play notes A, B, and C on beeper. ''(refer to beeper section for more details)''
-
-{{{
-# echo “W” > /dev/wt1 <CR>
-}}}
-Request weight from scale one.
-
-{{{
-# cat < /dev/wt1 <CR>
-}}}
-Display response to previous request from scale 1 as a weight structure converted to hexadecimal.
