| Description: | ||
| The maximum number of times the balloon driver will | ||

| Description: | ||
| The current number of times that the balloon driver | ||

| The default value is one. With max_retry_count being | ||

| Description: | ||
| The time (in seconds) to wait between attempts to | ||
| increase the balloon. Each time the balloon cannot be | ||
| increased, 'schedule_delay' is increased (until | ||
| 'max_schedule_delay' is reached at which point it | ||

| Description: | ||
|
|
||
| A generic interface for executing OLPC Embedded Controller commands and | ||
| reading their responses. | ||
|
|
||
| To execute a command, write data with the format: CC:N A A A A | ||
| CC is the (hex) command, N is the count of expected reply bytes, and A A A A | ||
| are optional (hex) arguments. | ||
|
|
||
| To read the response (if any), read from the generic node after executing | ||
| a command. Hex reply bytes will be returned, *whether or not* they came from | ||
| the immediately previous command. |
