SysComSettingsEx2 (STRUCT) ¶ TYPE SysComSettingsEx2 : STRUCT <category>Com port extended settings</category> <description>: This structure can be used to get and set the settings of a COM port. NOTE: The difference of this structure to SysComSettingsEx are the 2 members byDtrControl and byRtsControl! Here you can specify BYTE instead of BOOL values in SysComSettingsEx! </description> InOut: Name Type Comment byByteSize BYTE <element name=”byByteSize” TYPE=”IN”>Number of bits/BYTE, 4-8</element> bBinary BOOL <element name=”bBinary” TYPE=”IN”>Binary mode, no EOF check</element> bOutxCtsFlow BOOL <element name=”bOutxCtsFlow” TYPE=”IN”>CTS handshaking on output</element> bOutxDsrFlow BOOL <element name=”bOutxDsrFlow” TYPE=”IN”>DSR handshaking on output</element> byDtrControl BYTE <element name=”byDtrControl” TYPE=”IN”>DTR (data-terminal- ready) flow control.
