Howdy, I currently have a getty listening on COM1 to allow me to login to my Ultra 5 over a null modem cable. I'd like to expand this so that I can also access the boot process over the serial line (in addition to on the normal keyboard/monitor). Following the relevant chapter in the handbook (section 17.6), I find that they talk about the sio serial driver. I used the sab serial driver ... and it doesn't seem to have a man page. Are the same kernel options applicable to sab? For example, can I do something like this in my kernel config file: device sab0 at ebus0 port IO_COM2 flags 0x10 irq 43 ... ? Or is there some otehr process to enable the boot process on COM1 for sparc? My dmesg shows this, by the way: # dmesg | grep sab sab0: <Siemens SAB 82532 v3.2> addr 0x1400400000-0x140040007f irq 43 on ebus0 sabtty0: <ttya> on sab0 sabtty1: <ttyb> on sab0 Thanks for any help you can offer, -T -- Certainly the game is rigged.
