rs232AsyncPortBits

Module: RS-232-MIB

OID (symbolic): RS-232-MIB::rs232AsyncPortBits

OID (numeric): 1.3.6.1.2.1.10.33.3.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Description: The port's number of bits in a character.

What is rs232AsyncPortBits?

Sets the number of data bits per character on this asynchronous port, ranging from 5 to 8 -- an admin must match this to the far-end device's setting (typically 8) or received characters will come out garbled.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.10.33.3.1.2
snmpwalk -v2c -c public <target> RS-232-MIB::rs232AsyncPortBits

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.10.33.3.1.2.1
snmpget -v2c -c public <target> RS-232-MIB::rs232AsyncPortBits.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.2.1.10.33.3.1.2.1 i <value>
