Dear Tapan, This is the old problem: " Can't initialize modem h/w softcore:open: modem_init failed. Returning -1 " I must hard dig on Internet to check whether your "Silicon 537 [Windmodem]" board is indeed compatible with classic Intel 537 modem boards. As for now, would you please : $ cd intel-536-537/ $ sudo make uninstall $ reboot After reboot: $ dmesg | grep serial Note the ttySx devices $ stty -F /dev/ttySx -a Eventually: $ efax -d /dev/ttySx - http://vouters.dyndns.org:8080/ Philippe Vouters (Fontainebleau/France) Le mardi 30 juin 2009 à 11:30 +0530, Tapan Chugh a écrit : > Here is a part of the dmesg log probably from make install and all the > commands after it > > softserial:exit_module() > hamcore module cleanup > softserial:init_module() > hamcore module init > sound disabled > Intel 537EP card found > 537ep:softcore_init_struct: driver serial already allocated device. > 537ep:softcore_init_struct: Unregistering serial driver. > serial 0000:04:00.0: PCI INT A disabled > softcore: init struct done > softserial: venid 1543, dev 3052 > softserial_register_tty(): tty registered > softserial: init done > softserial:softserial_open() > softserial_open:caller efax[3494] > pci 0000:04:00.0: PCI INT A -> GSI 21 (level, low) -> IRQ 21 > Can't initialize modem h/w > softcore:open: modem_init failed.
