Hi Userid0, I tried to install the kernel source and kernel devel packages to match the kernel version but however i couldnt find the same version for kernel. I managed to upgrade the kernel to the latest level and installed kernel-headers and kernel- devel. after that i was able to to compile the driver package. now the issue is im testing the serial ports using minicom but still its not working. Is there anyway to verify the serial ports are detected. Below is the results im getting when open dev/tty [root@smsgateway ~]# ll /sys/class/tty/ console/ tty1/ tty17/ tty24/ tty31/ tty39/ tty46/ tty53/ tty60/ tty\_dgnc\_0\_1/ pr\_dgnc\_0\_0/ tty10/ tty18/ tty25/ tty32/ tty4/ tty47/ tty54/ tty61/ tty\_dgnc\_0\_2/ pr\_dgnc\_0\_1/ tty11/ tty19/ tty26/ tty33/ tty40/ tty48/ tty55/ tty62/ tty\_dgnc\_0\_3/ pr\_dgnc\_0\_2/ tty12/ tty2/ tty27/ tty34/ tty41/ tty49/ tty56/ tty63/ ttyS0/ pr\_dgnc\_0\_3/ tty13/ tty20/ tty28/ tty35/ tty42/ tty5/ tty57/ tty7/ ttyS1/ ptmx/ tty14/ tty21/ tty29/ tty36/ tty43/ tty50/ tty58/ tty8/ ttyS2/ tty/ tty15/ tty22/ tty3/ tty37/ tty44/ tty51/ tty59/ tty9/ ttyS3/ tty0/ tty16/ tty23/ tty30/ tty38/ tty45/ tty52/ tty6/ tty\_dgnc\_0\_0/ ---

You should be seeing /dev/ttyn1x ports on the host (as configured by UDEV). Make sure the jsm driver is not enabled in your new kernel: [http://knowledge.digi.com/articles/Knowledge\_Base\_Article/Digi-NEO-adapter-is-not-recognized-in-Linux/?q=dgnc&l=en\_US&fs=Search&pn=1](http://knowledge.digi.com/articles/Knowledge_Base_Article/Digi-NEO-adapter-is-not-recognized-in-Linux/?q=dgnc&l=en_US&fs=Search&pn=1) Next, make sure the adapter is initialized and the ports successfully created by looking in dpa.dgnc from the root prompt: # dpa.dgnc Let me know the results. ---

Hi, seems i cant attach the screen of the output from # dpa.dgnc but i am not sure if its working as expected. Sorry for being a noob here. My redhat version is as below. can you please verify if i have installed the right driver version.

What do you see in /var/log/messages for dgnc? cat /var/log/messages | grep dgnc ---

Have you tried another adapter slot in the host to see if the adapter is recognized? If this does not work, is the adapter recognized if put in the same slot as the working adapter? Typically, the inability to see the hardware points to a bad PCI(e) slot, BIOS resource issue, or a bad adapter. By switching around to differenct slots, including a known working slot, you should be able to narrow in on the problem.
