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"; }
