I believe I compiled the right drivers in to the kernel (actually, which two are the ones I see on the back of my PC?) ... device sio0 at isa? port "IO_COM1" tty irq 4 vector siointr device sio1 at isa? port "IO_COM2" tty irq 3 vector siointr device sio2 at isa? port "IO_COM3" tty irq 5 vector siointr device sio3 at isa? port "IO_COM4" tty irq 9 vector siointr .... but bootup messages don't seem very encouraging: Apr 9 03:35:08 meursault /kernel: sio0 not found at 0x3f8 Apr 9 03:35:08 meursault /kernel: sio1 not found at 0x2f8 Apr 9 03:35:08 meursault /kernel: sio2 not found at 0x3e8 Apr 9 03:35:08 meursault /kernel: sio3 not found at 0x2e8 And what was the kernel expecting to find on the serial line? Anyway, I went ahead and modified /etc/ttys to allow login over the serial interfaces: # Serial terminals ttyd0 "/usr/libexec/getty std.9600" unknown on secure ttyd1 "/usr/libexec/getty std.9600" unknown on secure ttyd2 "/usr/libexec/getty std.9600" unknown on secure ttyd3 "/usr/libexec/getty std.9600" unknown on secure .... and, firing up my terminal emulator from a machine on the other end of a serial connection (yes, I think I've got the null-modem hookup right), I get no response. Is there something more I need to do? Thanks for any help. daniel
