No joy here. I am trying the http://linmodems.technion.ac.il/packages/smartlink/slmodem-2.9.11-20070204.tar.gz version, with the slusb module for the usb modem. It compiles and runs fine for a brief time, but then locks up the modem and gives this message in the kernel.log: Feb 6 07:35:30 myhost st7554: fifo underrun! regards,
