Namespace: wclSerialClients
Delphi
type
 TwclSerialCommunicationState = (
 csCtsHold,
 csDsrHold,
 csRlsdHold,
 csXoffHold,
 csXoffSent,
 csEof,
 csTxim
 );

The TwclSerialCommunicationState type exposes the following members.

Show:
 NameDescription
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.

csEof

The end-of-file (EOF) character has been received.

csRlsdHold

Transmission is waiting for the RLSD (receive-line-signal-detect) signal to be sent.

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.

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.)
