The target connections are instruments that we can 'tip' to. Candidates are PCMCIA adapters (eg Quatech QSP-100), USB adapters (eg Keyspan, Comtrol Rocketport USB serial hub), or ethernet (eg Comtrol Rocketport ethernet serial hub, NPort server lite/pro). My preference is an ethernet adapter, since this sounds like it may be the easiest and most portable to use, though I have no idea how they work. Do you telnet them and then select a serial port to connect to, or do they use proprietary TCP/IP protocols and programs, or ??? Any advice or experience with any of these devices is appreciated; I'm running FBSD 4.3 (and not really interested in changing to -CURRENT, though I'm willing to back-hack anything that works).
