The EasyIO range of cards comes in 3 forms, the EasyIO-4, EasyIO-8 and the
|
||||
EasyIO-8M. All of these are non-expandable, low cost, ISA, multiport boards
|
||||
with 4, 8 and 8 RS-232C ports respectively. The EasyIO-8M is not currently
|
||||
supported by this driver. Though it is pretty easy to support so I'll do
|
||||
that when I get a chance. Each EasyIO board requires 8 bytes of IO address
|
||||
space and 1 interrupt. On an EISA system it is possible to share 1 interrupt
|

between multiple boards. The EasyIO-4 has 10 pin RJ connectors, and the

||||
EasyIO-8 comes with a dongle cable that can be either 10 pin RJ connectors or
|
||||
DB-25 connectors. The EasyIO-8M has 6 pin RJ connectors.

1.1 HOW TO GET BOARDS
|
||||
|
||||
Stallion Technologies has offices all over the world, as well as many more
|
||||
distributors and resellers. To find out about local availability please
|
||||
contact the nearest Stallion office and they can give you all the information
|
||||
you need. Look in the "Offices" file in the driver package for a current list
|
||||
of Stallion Technologies offices.
|
||||
|
||||
Another good source of information about the Stallion range of boards and
|
||||
local availability is on the Stallion Web page. Check it out at
|
||||
http://www.stallion.com.

you need is to have the full kernel source. Most people will have this

The driver can support up to 8 boards (any combination of EasyIO and

There is no real smart line discipline bypass code yet (like in the sio

I will probably also add LKM support some time soon.
