The following section has been causing me a few headache: http://www.freebsd.org/handbook/handbook118.html#183 1. My email address has changed to <andrew@pubnix.net> 2. People seem to be unaware of the difference between the Digiboard PC/8 and PC/8e and PC/8em I'd like to add the following paragraph (lines beginning with +) 10.3.3.2. Configuring the sio driver The sio driver provides support for NS8250-, NS16450-, NS16550 and NS16550A-based EIA RS-232C (CCITT V.24) communications interfaces. Several multiport cards are supported as well. See the sio(4) manual page for detailed technical documentation. Digiboard PC/8 Contributed by Andrew Webster <awebster@dataradio.com> . 26 August 1995. Here is a config snippet from a machine with digiboard PC/8 with 16550. + This configuration will only work for dumb digiboard cards, (PC/4 and PC/8) + it will not work for intelligent digiboard cards (PC/8e and PC/8em) - see + dgb(4) for details. It has 8 modems connected to these 8 lines, and they work just great. Do not forget to add options "COM_MULTIPORT" or it will not work very well! device sio4 at isa? port 0x100 tty flags 0xb05 device sio5 at isa? port 0x108 tty flags 0xb05 device sio6 at isa? port 0x110 tty flags 0xb05 device sio7 at isa? port 0x118 tty flags 0xb05 device sio8 at isa? port 0x120 tty flags 0xb05 device sio9 at isa? port 0x128 tty flags 0xb05 device sio10 at isa? port 0x130 tty flags 0xb05 device sio11 at isa? port 0x138 tty flags 0xb05 irq 9 vector siointr The trick in setting this up is that the MSB of the flags represent the last SIO port, in this case 11 so flags are 0xb05.
