I wrote one (driver) for myself and it works with full duplex.
The object code is less than 5K. I'll try to patch linux driver
but the limitation is that one of modes (read/write) should be 8 bit
and the other 16 bit(is this true for other cards?). I use one minor
number while others use /dev/dsp and /dev/dsp1 (i'm not sure if this was
case
with two cards). So which method is _correct_ ? ;-)
