Sirish, As your modem is serial based, it should work straight out with the native drivers. Try the following which is suggested by ModemData.txt: For candidate card in slot 08:00.0, firmware information and bootup diagnostics are: PCI slot PCI ID SubsystemID Name ---------- --------- --------- -------------- 08:00.0 1393:1045 1393:1045 Serial controller: Moxa Technologies Co Ltd CP-104EL-A Modem interrupt assignment and sharing: --- Bootup diagnostics for card in PCI slot 08:00.0 ---- === Finished firmware and bootup diagnostics, next deducing cogent software. === A candidate modem is not transparent among the PCI devices: ------------------------------------------------ 08:00.0 Serial controller: Moxa Technologies Co Ltd CP-104EL-A (4-port RS-232 PCI Express Serial Board) ------------------------------------------------ with USB, bridge, and RAM devices not displayed. If a High Definition Audio card is present, if might be hosted on the Subsystem. If your modem is an external USB type, connected by an external serial cable, or mounted internally on an ISA card, then scanModem would not access it. Try with Root permission ---> $ sudo wvdialconf /etc/wvdial.conf to detect these modem types and some USB modems. If the detection is successful, read the DOCs/wvdial.txt . Edit the /etc/wvdial.conf with Root permission: sudo gedit /etc/wvdial.conf will be able to dial out with Root permission: sudo wvdial Please do where the ----> is at, ---> $ sudo wvdialconf /etc/wvdial.conf and you should be able to access the modem through a /dev/ttyS* where * can be an integer 0 or greater which is the true modem port. Let us know if the above command was successful, otherwise wvdial may need to be installed or you may try out the graphical utilities kppp, NetworkManager, etc. Best Regards, Antonio On Tue, Dec 18, 2012 at 4:21 PM, Sirish Masur Mohan <Sirish.MasurMohan@xxxxxxxxx> wrote: > Hi, > > I installed a Moxa PCI express Multiport Serial Board on Ubuntu 12.04 with 3.2.0-33-generic kernel.
