Data type Description
UInt Flow control (Default value: 0):
1 = No flow control, 2 = XON/XOFF, 3 = Hardware RTS always ON,
4 = Hardware RTS switched
Char Specifies the character that is used as the XON character. This is typically a
DC1 character (11H). This parameter is only evaluated if flow control is
enabled. (Default value: 0)
Char Specifies the character that is used as the XOFF character. This is typically
a DC3 character (13H). This parameter is only evaluated if flow control is
enabled. (Default value: 0)
UInt Specifies how long to wait for a XON character after receiving a XOFF
character, or how long to wait for the CTS signal after enabling RTS (0 to
65535 ms). This parameter is only evaluated if flow control is enabled.
(Default value: 2000)
Bool TRUE for one execution after the last request was completed with no error
Bool TRUE for one execution after the last request was completed with an error
Word Execution condition code (Default value: 0)
