Hello! I have an old Sun E450 server and can't make console work. I tried both ttya and ttyb (I connect appropriate pins of Serial-to-USB cable and choosing output in Stop + A OpenBoot shell), tried different port speeds, tried resetting NVRAM by Stop+N etc. Nothing helps. Unfortunately, I can't connect VGA monitor because don't have an adapter and can't find it there in Russia, Moscow (an original Sun monitor don't know where to get too). Terminal emulation programs (minicom, screen) outputs garbage instead of text. I.e., boot process — garbage, I press Enter — garbage, I do command to net boot — rarpd and tftpd works OK, I see logs on Linux server, but I see garbage in serial console. How to fix, please advise.
