TApxProtocol.AbortNoCarrier

TApxProtocol

property AbortNoCarrier : Boolean

Default: False

Determines whether the protocol is canceled automatically when the DCD modem signal drops.

Using the AbortNoCarrier property is better than checking DCD and calling CancelProtocol in the user's own code. When this is done, the protocol engine sends a cancel sequence to the remote computer. If hardware flow control is enabled and the modem has lowered the DSR or CTS signals as well as DCD, the protocol waits several seconds before deciding it can't send the cancel command, leading to an unnecessary delay for the application. The AbortNoCarrier property prevents the protocol engine from sending the cancel sequence, so the protocol stops immediately.
