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
