11 FLOW CONTROL
This chapter contains information about
■Hardware and software flow control
■Received-data flow control
■Transmit-data flow control
Overview The Business Modem has two buffers, one for data transmitted from your
computer, and one for data received from the phone line.
Flow control provides a system for stopping and starting transmission
depending on how full the buffers are. Flow Control’s purpose is to
prevent overfilling the buffers, which may cause data to be lost.
We recommend that you use hardware flow control. If you do,
depending on your communications software, you will also need to
enable hardware flow control in your communications software.
