rs232PortOutFlowType

Module: RS-232-MIB

OID (symbolic): RS-232-MIB::rs232PortOutFlowType

OID (numeric): 1.3.6.1.2.1.10.33.2.1.8

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The port's type of output flow control. 'none' indicates no flow control at this level. 'ctsRts' and 'dsrDtr' indicate use of the indicated hardware signals.

What is rs232PortOutFlowType?

Controls the port's outbound flow-control method: none(1) disables hardware flow control, ctsRts(2) uses the CTS/RTS signal pair, and dsrDtr(3) uses DSR/DTR instead -- a common fix when a serial link is dropping or garbling data under load.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.10.33.2.1.8
snmpwalk -v2c -c public <target> RS-232-MIB::rs232PortOutFlowType

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.10.33.2.1.8.1
snmpget -v2c -c public <target> RS-232-MIB::rs232PortOutFlowType.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.2.1.10.33.2.1.8.1 i <value>

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> rs232PortOutFlowType.1
