2.13 CAN Timeout Commands
It is possible, under heavy CAN bus loads or faulty CAN bus, to place the unit in a state where no more
input parsing from the COM port can occur due to the internal buffers being full and the CAN TX not being
able to proceed. Under this condition, a config command cannot be processed. This is to ensure that no
CAN messages are lost while waiting for the CAN bus to become available.
In order to prevent this, a timeout parameter can be specified that will ensure additional input parsing can
occur at the expense of some CAN messages. This will allow a CONFIG command sequence to be
recognized even when the CAN bus is overloaded or faulty.
The command to set/get the timeout follows:
get can timeout: Gets the timeout setting.
set can timeout can_tx_busy=off: Disables timeout, will wait indefinitely (default)
set can timeout can_tx_busy=1000: Sets the timeout (10 to 10000 ms)
