Hi list,
I am very much tired with the following problem, and
so with very high hopes i am approaching the news
group.
My problem is such,
I am a isp , i used the specialix i/o 8+ cards for
people to dial-in on my modems. The driver for the
specialix cards are avialable as modules with the
precompiled kernel of redhat. But for the pci version
of the card, the driver is only available with 2.0.38
kernel on-wards.
Now i have to have a different type of specialix card
"the SX" card which is a 16 port pci/isa card.
I have followed exactly as the manufacturers have
suggested in the help file for loading drivers for sx
cards in linux. I am able to get the kernel recognise
the card and the channels(ports). But the problem
starts here that when i use mgetty to allow dialin on
my modems i do not get the correct response.
After a lot of trouble the cabling (interface) between
the 16 port board and the modem was found to be
incorrect. i have changed the cabling interface as
prescribed by the specialix company. now i encounter a
different problem. I dont get the DTR(high) signal on
the modem on connecting to the board. but when i dial
it gets connected , the DTR signal goes high and i am
able to surf, every thing seems fine.
After disconnecting the DRT goes low again the RD&TD
signal remain continiously high, and i cannot dial
again to the modem cause it gives me a busy.
Also the server shows that the user is still logged in
i.e that tty is still active. if i kill the bash,
login on that tty the modem returns to the default
state ie without the DTR high.
Now guys i desperately need help cause i am frustrated
if any one of u have done this before please let me
know i will treat u ( HONEST). i dont understand what
is the problem, could it be wrong cabling interface, i
just don't know.
i am also giving the interface pin configuration that
i am using
Specialix DLINK
