.Sh NUMBERING
|
|
|
|
|
Only one line for each card is needed in the kernel configuration file.
|
|
|
|
|
The first card's ports will be installed from sr0. The numbering of the
|
|
|
|
|
next card will continue where the first stopped, eg. if the first card
|
|
|
|
|
is a two port card it will use sr0 and sr1. The next card will then
|
|
|
|
|
start at sr2.
|
|
|
|
|
.Pp
|
|
|
|
|
The card only supports IRQ 3, 4, 5, 7, 10, 11, 12 and 15.
|
|
|
|
|
.Pp
|
|
|
|
|
The iomem area is a 16Kb block and must start at a 16Kb boundary.
|
|
|
|
|
.Pp

|

.Sh DIAGNOSTICS
|
|
|
|
|
.Bl -diag
|
|
|
|
|
.It "sr%d: Warning illegal interrupt %d."
|
|
|
|
|
The card cannot use the specified interrupt. Choose a different one.

.Sh BUGS
|
|
|
|
|
At the moment only the X.21 interface is tested. The others
|
|
|
|
|
may need tweaks to the clock selection code.
|
|
|
|
|
.Pp
|
|
|
|
|
The code can probably stand some optimizing.
