Flow Control

Purpose: Regulates the data transmission through the communications port. The reader
is a DTE device.
Clear To Send/Request To Send (CTS/RTS) is a hardware signal flow control.
The reader sets RTS high when it is ready to transmit. The reader checks CTS
when it tries to transmit data.
XON/XOFF response causes the reader to respond to XON/XOFF characters
received while transmitting. XON/XOFF control specifies that the reader
transmits XON/XOFF characters to control the incoming data flow.
XON/XOFF response and control specify that the reader responds to and
transmits XON/XOFF characters.
Note: You must select the communications port and protocol before you set the
parameters that define the protocol. For help, see "Communications Protocol,
Configure" earlier in this chapter.
