How to set octed string in Hex bytes in SET command?

Net-snmp-5.5-1.x86.exe for Win32

I need set IP addreess in HEX format, separated by whitespace, using NET-SNMP set command. 
For example, an IP address 192.168.100.100 converted to Hex format is 0xC0A86464

192.168.100.100 > 0xC0A86464

The correctly set value should return the following value when check with snmpget:

xxx-xxx-xxx-MIB::docsDevServerAddress.0 = Hex-STRING: C0 A8 64 64

I tried
snmpset -v 1 -c private 192.168.100.5 docsDevServerAddress.0 x 0xC0 A8 64 64

But when I using this format to set HEX address, I always got errors like this: 'A8: Bad object type: 6', or '00xA8 Bad object type: 0', and so on, depending on representation of hex format I tried.
According to NET-SNMP manual, 'x' is octet string in hex bytes, separated by whitespace.

What is correct input format for SNMPSET to set Hex values I need?

Best Regards,
