A compact tool (100) for network radios implementing bidirectional data communication links in computer networks. The tool is formed of a compact chassis or body (101) that can be conveniently stored in a user's pocket. A control processor (502) contained within the chassis is coupled to a data network communications module (506), including an integrated connector (616). The control processor (502) and data network communications module is configured exclusively for communicating with the network radio. Such interface communications are performed using Simple Network Management Protocol (SNMP) and/or telnet protocols. Using these communication protocols, the tool (100) can access radio operating data stored or generated by the network radio. The operating data is displayed using a simple integrated display device (514, 614).
