I'm glad I could help, but I think I need to make a little further clarification of something I don't think I adequately explained. The RS232 interface is the physical serial interface on the back of the unit, very similar to the RS232 serial interface on the back of your workstation. In most cases, a cable is connected directly to the serial interface, requiring the operator to be present at the same location as the unit. Alternately, some devices allow a form or remote management my allowing for a modem to be connected to the RS232 port, allowing the operator to dial up the unit from a remote location. In my discussion of TELNET, and so forth, I was referring to in-band network management. This allows the operator to access the device via the same network that the device is providing service to, no other equipment or cables are necessary. In most implementations, TELNET allows the operator to remotely use the same user-interface in the same way as it would be used it the operator were present at the location of the device using a cable attached to the RS232 serial port. TELNET, SNMP, RMON, and built-in web servers are all examples of in-band network management systems, in that they don't require a separate physical connection to the managed device. I'm not exactly certain what Nathanc meant by the words "brought down". If he's referring to the device being physically uninstalled, reconfigured and replaced, the only situation I could envision where this would be necessary would be in some sort of tower or pole-top installation. However, none of the current Wi-LAN products appear to be housed in suitable environmental enclosures, so I don't believe this is a likely scenario. In any case, I don't believe that the product is likely to be configured and reconfigured at frequent intervals. By their nature, transparent MAC bridges are devices which are installed once and largely forgotten.
