Hi, Having just purchased and built a YAM9K6 modem, I tried to get it working on my Linux system : RH 6.1, 2.2.13 Kernel, etc. The yamcfg yam0 bit seems to work just fine, but when I try using ifconfig, it fails and refuses to bring the interface up. I can use ifconfig to set device name, HW, callsign, etc without errors, but setting the IP address gives 'SIOCSIFFLAGS: Input/output error' although it does seem to set the IP address, as seen by doing 'ifconfig yam0' I get the same error when I try doing 'ifconfig yam0 up' and the interface remains down. Anyone got any clues please ? Also are there any good WWW resources around concerning YAM and LINUX ? What I could find doing searches wasn't very enlightening.
