It look to be the opposite pin assignment like a modem, but further studies have shown, that it is non-standard. I have soldered 8x adapters from 25-female to 25-female but with the SUN compatible pin out ! This is the same as on the PC (25pin) but female instead of male ! The following wirering is necessary to have a PC or SUN compatible connector: MUX side PC/SUN like connector 3.......2 2.......3 8.......4 22......5 20......6 7.......7 4.......8 6.......20 9.......22 So you can use a simple NULL-Modem cable to connect the PC to the PC/SUN compatible MUX connector. For simple serial console you can use following: Only use pins 2,3 and 7, where 2=RX, 3=TX and 7=GND ! If you use NOT a UNIX-like system on the PC the bridge CTS and RTS pins on the PC side. On my E55 only port 0 (first connector) is used for the serial console. With friendly regards Christoph P.
