I have a solution, but it's alpha, and I'm building hardware to solve the problem. I'm using buffered circuits to sniff the serial RS232 connection, and put both half-duplex streams into a microprocessor with 3 serial ports, one for each end of the half-duplex connection (recall 2 half-duplex connections make one normal RS232 full duplex circuit). Then the third serial port will stream the data to another serial port on a pc. At that point you have both streams so you can do as you wish with them. The circuits work, but it requires +12 Vdc and +/- 5Vdc. I'm waiting on the power supply chips to arrive to finish the prototype. Phase 2 is to add an ethernet(realtek 8019) chips to the micro so you don't need a free serial port on a pc to use. It's about 2 months away form being ready for field testing, but, anyone interested could drop me a line or 2 as I'll be looking for beta testers.... I designed it to reverse engineer (proprietary over RS232) protocols used in industrial environments (vendors in this space are unbelievable pains in the a_ _), but, I'm sure it's gonna have many, many uses..... particularly for those with 'inquiring minds'..... and RS232 challenges. I'm also contemplating extremely low power miniturization and rf, if there is a market. Ideas are most welcome. James -- gentoo-user@gentoo.org mailing list
