Experimental Physics and Industrial Control System
Hi all,
I have problems reading the output from my serial device using streamDev
my protocol is
thr_low_valid_intr {
Terminator = LF;
cc="thr_low_valid";
in $recvKey $cc" %*x %{INVALID|VALID}";
}
my record is:
record(bi, "etrax201:RLTH:thr_low_valid") {
field(DESC, "thr low valid")
field(SCAN, "I/O Intr")
field(DTYP, "stream")
field(INP, "@hadcon_RLTH.proto thr_low_valid_intr()
$(device,undefined)")
field(VAL, "0")
field(ZSV, "MINOR")
field(ZNAM, "INVALID")
field(ONAM, "VALID")
}
"device" set in st.cmd
but the result (var streamDebug 1) is that VALID or INVALID is not
recognized:
2010/07/23 16:52:35.449 hadcon AsynDriverInterface.cc:983:
AsynDriverInterface::asynReadHandler(etrax201:RLTH:thr_low_valid,

ioAction=AsyncRead
2010/07/23 16:52:35.451 hadcon StreamCore.cc:910:

2010/07/23 16:52:35.459 hadcon AsynDriverInterface.cc:674:
AsynDriverInterface::readRequest(etrax201:RLTH:thr_low_valid, 4000
msec reply, 500 msec read, expect 0 bytes, asyn=yes)
2010/07/23 16:52:35.464 hadcon AsynDriverInterface.cc:1067:
AsynDriverInterface::asynReadHandler(etrax201:RLTH:thr_low_valid)
readMore=0, ioAction=AsyncRead
The rest of the protocol is working just this function not, why?
Any suggestions appreciated,
best regards,
Peter
