Experimental Physics and Industrial Control System
Boy how I hate bringing this stuff up on a Friday...
I have a need to communicate to a serial based instrument off of a
windows laptop. I have the latest ASYN build, which supports COM port
mapping for windows. Like any 'modern' laptop, this machine does not
have any built in serial connections, so I have a USB adapter which maps
COM3 to a serial port. I can talk to the device via a terminal program
on machine.
I execute the following on a softIOC running on the windows box:
drvAsynSerialPortConfigure("L0","COM3",0,0,0,0)
asynSetOption("L0",0,"baud","115200")
setOption failed COM3 error calling GetCommConfig 87
Note the setOption failed error; this is (apparently) preventing me from
setting the baud rate to 115.2K (which, of course, is what the external
device needs). (As an aside, I contacted Mark Rivers and he pointed out
the typo in the error message - it should read: "...error calling
SetCommConfig...")
I know this adapter handles that baud rate, as I can set it via a
terminal program and communicate to my external device.
Any ideas?
