Hi Jan
Could you provide ioc shell output with ioc start up and the error messages?
It is usually very handy if asyn trace output is included. To do so, put these : 

asynSetTraceIOMask("$(PORT)",0,4)
asynSetTraceMask("$(PORT)",0,9)

into you startup script before iocInit().

Předmět: Stream device problem with redirection in @mismatch

Hi all,
I have a device that sends a response on command
"on/off" (requested value) or "INTERLOCK").
I use a @mismatch exception handler and redirection to record in
order to catch this "INTERLOCK" string. After that I turn on or off the
LED widget
(Interlocked or Non-Interlocked). When I started IOC it gave me a buffer 
overflow.
Buffer overflow is appeared after adding arg: (\$2).

DB and proto file are following:


DB:


# requested value laser state
record(bi, "$(device):StatEnable")
{
     field(DESC, "Laser Enabled")
     field(DTYP, "stream")
     field(INP,  "@fibotecLtbis.proto
get_enable($(channel),$(device):StatEnableInterlock) $(port)")
     field(SCAN, "1 second")
     field(ZNAM, "Off")
     field(ONAM, "On")
     field(PINI,"YES")

}
#makro
#channel=1
#device=name:ch1

#
#Catching INTERLOCK message


record(bi, "$(device):StatEnableInterlock")
{
     field(DESC, "Laser Enabled")
     field(ZNAM, "INTERLOCK")
     field(ONAM, "Ok")
     field(VAL, "1")
     field(PINI,"YES")

}

Proto file:

get_enable  { out "get ch\$1 status"; in "get ch\$1 status\r\r\n =
%{off|on } ";
@mismatch {in "get ch\$1 status\r\r\n%(\$2){INTERLOCK}";}}


Thanks Jan
