asynOctetClient::asynOctetClient	(	const char *	portName,
		int	addr,
		const char *	drvInfo,
		double	timeout = `DEFAULT_TIMEOUT`
	)

inline

Constructor for asynOctetClient class.

Parameters

[in]	portName	The name of the asyn port to connect to
[in]	addr	The address on the asyn port to connect to
[in]	drvInfo	The drvInfo string to identify which property of the port is being connected to
[in]	timeout	The default timeout for all communications between the client and the port driver

◆ asynOctetClient() [2/2]

asynOctetClient::asynOctetClient	(	const char *	portName,
