### Description

```asn1
fcfLineV28AsynInDceEnablingSig1 OBJECT-TYPE
SYNTAX INTEGER {
none(1),
rts105(9),
dtr108(33),
rts105-dtr108(41)
}
ACCESS read-write
STATUS mandatory
DESCRIPTION
"The value of this object defines which circuits
are scanned to determine whether this serial line
interface is up or down. Secondary circuits may
also be simultaneously scanned (see
fcfLineV28AsynInDceEnablingSig2).
none : the circuits 105, 108 are not used. If
also the circuits 111, 140 and 141 are not
used the state of this interface is
determined by another method,
rts105 : the circuit 105 (request to send) is
used,
dtr108 : the circuit 108 (108/1 connect data
set to line, 108/2 data terminal ready) is
used,
rts105-dtr108 : both circuits 105 and 108 are
used.
The default value is 'rts105'."
