The enumeration describes state of the serial communication device.
| Enumerator |
|---|
| csCtsHold | Transmission is waiting for the CTS (clear-to-send) signal to be sent.
|
| csDsrHold | Transmission is waiting for the DSR (data-set-ready) signal to be sent.
|
| csRlsdHold | Transmission is waiting for the RLSD (receive-line-signal-detect) signal to be sent.
|
| csXoffHold | Transmission is waiting because the XOFF character was received.
|
| csXoffSent | Transmission is waiting because the XOFF character was transmitted. (Transmission halts when the XOFF character is transmitted to a system that takes the next character as XON, regardless of the actual character.)
|
| csEof | The end-of-file (EOF) character has been received.
|
| csTxim | There is a character queued for transmission that has come to the communications device by way of the TransmitCommChar function. The communications device transmits such a character ahead of other characters in the device's output buffer.
