/* NOTES:
|
|
|
|
This driver was written for the Dynalink IS64PH ISDN TA, based on two
|
|
Siemens chips (HSCX 21525 and ISAC 2186). It is sold in the Netherlands.
|
|
|
|
model numbers found on (my) card:
|
|
IS64PH, TAS100H-N, P/N:89590555, TA200S100045521
|
|
|
|
chips:
|
|
Siemens PSB 21525N, HSCX TE V2.1
|
|
Siemens PSB 2186N, ISAC-S TE V1.1
|
|
95MS14, PNP
|
|
|
|
plug-and-play info:
|
|
device id "ASU1688"
|
|
vendor id 0x88167506
|
|
serial 0x00000044
|
|
i/o port 4 byte alignment, 4 bytes requested,
|
|
10 bit i/o decoding, 0x100-0x3f8 (?)
|
|
irq 3,4,5,9,10,11,12,15, high true, edge sensitive
|
|
|
|
At the moment I'm writing this Dynalink is replacing this card with
|
|
one based on a single Siemens chip (IPAC). It will apparently be sold
|
|
under the same model name.
|
|
|
|
This driver might also work for Asuscom cards.
