Proxima ASA 7910, 7911 manual

CTS pin, notifying the remote RS-232 host that data may be sent over the connection. This function regulates the data exchange between two RS-232 hosts.

In addition to this basic function, the Serial Adapter’s flow control options regulate the data exchange between the Serial Adapter and its attached RS-232 host. Below is a short descrip- tion of how each flow control option operates when enabled:

Generate XON/XOFF: When its buffers are full, the Serial Adapter will send an XOFF character to the attached host as a signal for the host to stop transmitting data to the unit. Once space becomes available within its buffers, the Serial Adapter will send an XON character to the host as a signal to begin transmission.

Recognize XON/XOFF: If the Serial Adapter receives an XOFF character from the host, it will stop sending data to the host. When it receives an XON from the host, the Serial Adapter will resume transmission.

Generate CTS: The Serial Adapter will inhibit the CTS pin if its buffers become full, and assert CTS if there is room in its buffers.

Generate DSR: The Serial Adapter will inhibit the DSR pin if its buffers become full, and assert DSR if there is room in its buffers.

Recognize DTR: The Serial Adapter will not send data to the host unless the DTR pin is asserted.

Recognize RTS: The Serial Adapter will not send data to the host unless the RTS pin is asserted.
