Navid, Being unable to reuse the modem in a single session is a known problem with the slamr driver, since a kernel change some time ago. Which driver are you using? With respect to being unable to intially get slmodemd function, try shutting down as many other functions as possible. $ cat /proc/interrupts or running ./scanModem will show which IRQ sharings may be cogent. Modem isof the lowest priority under current Linux. After bootup do $ dmesg > dmesg.txt Browsing dmesg.txt will show that PCI modem hardware is among the last configured.
