j
Success Response
A[config]
| [config] | Four ASCII-hex characters specify the directions of the channels of the module. A "1" in any bit means that the corresponding channel is configured as an output. A zero in any bit means that the corresponding channel is configured as an input. This command returns a zero for any bit that does not correspond to a channel. For example, if the command is sent to an eight-channel module, it returns configuration data for the lowest eight bits and zeros for the highest eight bits. |
