Description: The number of input signals for the port in the input signal table (rs232PortInSigTable). The table contains entries only for those signals the software can detect and that are useful to observe.

What is rs232PortInSigNumber?

Reports how many input control signals (like CTS or DSR) this port exposes in the input signal table, i.e. only those the hardware/software can actually detect and that are worth monitoring.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.10.33.2.1.3
snmpwalk -v2c -c public <target> RS-232-MIB::rs232PortInSigNumber

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.10.33.2.1.3.1
snmpget -v2c -c public <target> RS-232-MIB::rs232PortInSigNumber.1
