Subject: stream enum

Hi all,
   I met some little question about stream.
   After I sent command, I received a sequence of character through stream.
   The pv type was stringin and the value of the pv was 1(string) or 0(string).
   My question was that, I need the pv value was natural number( 0 or 1 ), not string type.
   I have tried to change the stringin to ai, some error came out. Then I think I could use the enum, but I could not know the usage though I tried.
   Could someone give some help.

Thanks,
Li xing

My db and proto file.
---------------------------------------------------------------
record(stringin, "$(P)$(R)STAT")
{
    field(DESC, "test")
    field(DTYP, "stream")
    field(INP,  "@devplc2.proto STAT $(PORT) $(A)")
}

STAT{
    out "\x0500FFBR2Y0000402F";
     in "\x02%*4s%c%*c%*c%*c%*c%*c%*c%*c%*c%*c%*s";
}
