There is special Windows software for managing Natex MUXes. It works with those MUXes via an RS232 port only. I want to be able to run it from a remote location. Solution 1. A hardware RS232 portserver (e.g. Moxa) and a special Windows driver for COM-port redirection. Works great. Disadvantage: it's pretty expensive and occupies additional rack space. Solution 2. Using an existing networked FreeBSD box sitting next to the MUX, it already has COM ports. Advantage: cheap, no additional rack space and power. Disadvantage: doubts if this solution is feasible, especially on the Windows side. A minicom or any other interactive terminal emulation software is out of the question. The MUX managing software uses its own protocol over RS323 and insists that it be a "real" port. Perhaps my English is so poor that I could not present the task correctly from the very beginning.
