txRxPacket

• Syntax ``` cs void txRxPacket(int port_num, int protocol_version)

- Parameters

| Parameters       | Description      |
|:-----------------|:-----------------|
| port_num         | Port number      |
| protocol_version | Protocol version |

- Detailed Description

   This function calls either `txRxPacket1` or `txRxPacket2` function depending on the `protocol_version`. The function stores data for being written into the array for packet transmission and gets data read from rx buffer of #`port_num` port by `txPacket` and `rxPacket` functions. When `txPacket` function succeeds to communicate, it will continue to `rxPacket` and finishes the process if the packet succeeds to be received. In particular, the group handler functions for write, such as SyncWrite, and BulkWrite, don’t use `rxPacket` so the function finishes its operation immediately after the 'txPacket2'. Before the `rxPacket`, it sets packet timeout if the instruction of received packet is for read. The communication result and the hardware error are available when the function is terminated.
