Marc, >From the dmesg data, there are some severe resource conflicts, at least under your older 2.6.18 kernel. You might try using the alternate ltmodem packages at http://linmodems.technion.ac.il/packages/ltmodem/kernel-2.6/ the ltmodem-20080619.tar.gz or ltmodem-20090420.tar.gz These provide resources for compiling a ltmodem.ko ltserial.ko driver pair, to be loaded in order: # modprobe ltmodem # modprobe ltserial and the port name is /dev/ttyLTM0 Read the included documentation carefully.
