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)
readMore=0, ioAction=AsyncRead

The rest of the protocol is working just this function not, why?
Any suggestions appreciated,
best regards,
Peter
