Table C-9. Asynchronous Port Table Objects (2 of 2)
Object Setting/ContentsDescription
rs232AsyncPort
Parity
(rs232Async
PortEntry 4)
Specifies the type of parity
used by the port. Supports only the following values:
none(1) – No parity bit
odd(2) – Odd parity
even(3) – Even parity
rs232AsyncPort
AutoBaud
(rs232Async
PortEntry 5)
Specifies the ability to
automatically sense the
input speed of the port.
Supports only the following values:
disabled(2) – Does not support
Autobaud.
Synchronous Port Table Objects
The Synchronous Port Table Objects contains an entry for the synchronous user
data port and the Management port when this port is configured for synchronous
operation. For this unit, entries in the table that are counters (rs232SyncPortEntry
3–7) are used to collect statistics only and are not supported. Clarification for
objects contained in this table as it applies to the unit is provided below.
Table C-10. Synchronous Port Table Objects (1 of 2)
Object Description Setting/Contents
rs232SyncPort
ClockSource
(rs232Sync
PortEntry 2)
Specifies the clock source
for the port. Supports only the following values:
internal(1) – The port uses an internal
clock.
split(3) – The port uses an external
transmit clock and internal receive clock.
rs232SyncPort
Role
(rs232Sync
PortEntry 8)
Specifies whether this
device interface is a DTE or
DCE.
Supports only the following value:
dce(2) – The port acts as a DCE.
rs232SyncPort
Encoding
(rs232Sync
PortEntry 9)
Specifies the bit encoding
technique that this port
uses.
Supports only the following value:
nrz(1) – The port uses non-return to
zero encoding.
rs232SyncPort
RTSControl
(rs232Sync
PortEntry 10)
Specifies the method used
to control the RTS signal.
Refer to Data Port Options,
Table A-3.
Supports only the following values:
controlled(1) – For User Data port, this
value is used when the Data Port option
Carrier Control by RTS is set to
Switched.
constant(2) – For User Data port, this
value is used when the Data Port option
Carrier Control by RTS is set to
Constant. This is the only valid value for
the Management port.
