Re: No reply from device using asyn+streamdevice

asynSetTraceMask(“D1”,0,0x9) — bit 0 enables error messages, bit 4 enables diagnostic messages from the driver level.

asynSetTraceIOMask(“D1”,0,0x2) — bit 1 arranges for characters read from and sent to the instrument to be displayed as ASCII characters with C-style escape sequences.

The messages in your message indicate that nothing is being received since there are no characters between the pair of double quotes.

I have added the following to  st.cmd file after configuring the port:

asynSetTraceIOMask(“D1”,0,0x2)

asynSetTraceMask(“D1”,0,0x9)

but the prompt as follows

2018/10/09 10:36:45.340114 D1 Va1: Input "" too short.

2018/10/09 10:36:45.340135 D1 No match for ":"

2018/10/09 10:36:50.340043 D1 No match for ":"

I have three questions:1) what is the meaning of  mask in asynSetTraceIOMask and asynSetTraceMask? 2) I see the definition of the mask in asynDriver.h 

	/* traceMask definitions*/
	#define ASYN_TRACE_ERROR 0x0001
	#define ASYN_TRACEIO_DEVICE 0x0002
	#define ASYN_TRACEIO_FILTER 0x0004
	#define ASYN_TRACEIO_DRIVER 0x0008
	#define ASYN_TRACE_FLOW 0x0010
	#define ASYN_TRACE_WARNING 0x0020

	#define ASYN_TRACEIO_NODATA 0x0000
