lsi record for more than 40 characters doesn't work

[dmnr infn via Tech-talk <tech-talk@aps.anl.gov>]

Hi all,

I have a .db e .proto made in this way:

.db

record(lsi, "RF:getString")
{
    field(DESC, "String more than 40 chars")
    field(SIZV, "80")
    field(INP, "@MDO.proto getString L0")

    field(SCAN, ".2 second")
}

.proto
getString {
    out "STT?";
    in "%s";
}

I want to get a String that is more than 40 characters, and I use a lsi record but I got always 40 chars.

There is something wrong in my code?

Thank you
