Hardware manual

BB-1004 and BB-1008 do not support DCD and RI lines, and thus are not usable for dialin modems. They
will work fine for all other purposes.
Digi PC/8 Interrupt Status Register is at 0x140.
SIIG IO1812 manual for the listing for COM5-COM8 is wrong. They should be COM5=0x250,
COM6=0x258, COM7=0x260, and COM8=0x268.
5.8 Intelligent Multiport Serial Boards
Make sure that a Linux-compatible driver is available and read the information that comes with it. These
boards use special devices (in the /dev directory), and not the standard ttyS ones. This information varies
depending on your hardware. If you have updated info which should be shown here please email it to me.
Names of Linux driver modules are *.ko (*.o prior to kernel 2.6) but these may not work for all models
shown. See Modules (mostly for smart boards) The needed module may have been supplied with your Linux
distribution. Also, parameters (such as the io and irq often need to be given to the module so you need to find
instructions on this (possibly in the source code tree).
There are many different brands, each of which often offers many different cards. No attempt is currently
being made to list all the cards here (and many listed are obsolete and have bad internet links to them which
need to be fixed). But all major brands and websites should be shown here so it something is missing let me
know. Go to the webpage shown for more information. These websites often also have info (ads) on related
hardware such as modem pools, remote access servers (RASs), and terminal servers. Where there is no
webpage, the cards are likely obsolete. If you would like to put together a better list, let me know.
