OS: RHEL 6.6
I recently purchessed two Digi NEO PCIe 8 port cards with the Acceleport 16 RJ45 Rack box. I placed both cards into pcie slots, and then cabled them to the Acceport using the cables that where provided. I turned on my server. I would think that I would have 16 /dev/ttyS*, but there are only the standard 4.
I did an
lsmod | grep jsm
Nothing returned back, meaning that the jsm driver didn't load at boot time. I rebooted the machine again, and still I do not see either the jsm driver loaded, or the /dev/ttyS* devices.
I can do a modprobe jsm and it appears to load the driver, but I still don't have any /dev/ttyS*.
PCI has been enabled in the BIOS.
I did an lspci, and the Digi Neo is found and labeled as a serial controller. It looks like there is also a Intel Serial controller on the motherboard as well. But I think the main problem is that the jsm driver is not loaded.
