The soft modem Motorola sm56 - PCI Device 1057:3052 - can be used with slamr & slmodemd with a simple patch to amrmo_init.c (under drivers directory): [zello@zello drivers]$ cat 1057_3052.patch 139,141d138 < /* Motorola */ < #define PCI_VENDOR_ID_MOTOROLA 0x1057 < 237,238d233 < {PCI_VENDOR_ID_MOTOROLA, PCI_DEVICE_ID_SL1900, /* 1057:3052 */ < PCI_ANY_ID, PCI_ANY_ID, 0, 0, SL1900_CARD}, Although some errors, I've been able to connect (using kppp on /dev/ttySL0) at 33600 bps. Can you help me to connect at 56600? Thanks, bye -- zello
