Smartlink AMR laptop modem and setserial
 

RH8.0 installed fine on my laptop, but did not detect the Smartlink modem. So I got the Linux Smartlink driver (ftp.smlink.com/linux), compiled and installed it. The modem works fine (on /dev/ttySL0), but it seems a bit slow. So I tried to check it with:

setserial -agv /dev/ttySL0

but got:

Cannot get serial info: Invalid argument

So I tried:

stty -F /dev/ttySL0

and it gave:

speed 115200 baud; line = 3;
min = 1; time = 0;
ignbrk -brkint -icrnl -imaxbel
-opost -onlcr
-isig -icanon -iexten -echo -echoe -echok -echoctl -echoke

I noticed here that the speed is OK, but there is no crtscts entry. The slowness can be a symptom of no hardware flow control, so is is possible to set hardware flow control on this modem? And why does setserial fail?

lspci please ?

Well, the speed seems to be better now (ISP was slow I think), but here is my lspci:

I upgraded the kernel to 2.4.26, and all problems went away. But I have broadband now ;-)
