Flow Control<br />

Purpose: Regulates the data transmission through the communications port. The reader<br />

is a DTE device.<br />

Clear To Send/Request To Send (CTS/RTS) is a hardware signal flow control.<br />

The reader sets RTS high when it is ready to transmit. The reader checks CTS<br />

when it tries to transmit data.<br />

XON/XOFF response causes the reader to respond to XON/XOFF characters<br />

received while transmitting. XON/XOFF control specifies that the reader<br />

transmits XON/XOFF characters to control the incoming data flow.<br />

XON/XOFF response and control specify that the reader responds to and<br />

transmits XON/XOFF characters.<br />

Default: None<br />

12-56<br />

Note: You must select the communications port and protocol before you set the<br />

parameters that define the protocol. For help, see “Communications Protocol,<br />

Configure” earlier in this chapter.<br />
