====== Set RS232 ======
''Set RS232 channel, baudRate, protocol''
| //channel// |RS232 Channel (1 to 3)  |
| //baudRate// |BaudRate (Must be a constant; cannot be a variable.)  |
| //protocol  // |Protocol (Must be a constant; cannot be a variable.)    |

You can only use the [[cubloc:opencom:|OpenCom]] command once to open a serial port. ''Set
RS232'' is used to change the baud rate and/or protocol of a serial port at run time.

For the protocol parameter, please refer to the table below:

^ Bit7  ^ Bit6  ^ Bit5  ^ Bit4    ^ Bit3          ^ Bit2           ^ Bit1  ^ Bit0       ^
|       |       |       | Parity  |               | Stop Bit       | Bit   | # of Bits  |
|       |       |       | 0       | 0 = NONE      | 0=1 Stop Bit   | 0     | 0 = 5 bit  |
|       |       |       | 0       | 1 = Reserved  | 1=2 Stop Bits  | 0     | 1 = 6 bit  |
|       |       |       | 1       | 0 = Even      |                | 1     | 0 = 7 bit  |
|       |       |       | 1       | 1 = Odd       |                | 1     | 1 = 8 bit  |

The following table shows typical settings based on the previous table:

^Bits ^Parity ^Stop Bit ^Value to Use^
|8 |NONE |1 |3|
|8 |EVEN |1 |19 (Hex = 13)|
|8 |ODD |1 |27 (Hex = 1B)|
|7 |NONE |1 |2|
|7 |EVEN |1 |18 (Hex = 12)|
|7 |ODD |1 |26 (Hex = 1A)|
