Hi!

There was an Ubuntu 9.04 system with MOSCHIP 9865 chipset PCI serial adapter. I've built the kernel module MCS9865 Ver1.1 and it worked normal.

After I have upgraded the system to Ubuntu 12.04 with kernel v3.2 there was difficulties when rebuilding kernel module but I solved them as proposed in this page.

The 'mcs9865.ko' kernel module loads OK but without any notification and 'ttyD*' device creation. Using commands

didn't help.

Any suggestion would be appreciated.

I'm running on 12.04 with two MCS9865 cards with two serial ports . When I was running on an older version of Ubuntu I had to compile the MCS9865.c hacking it to fit with later versions of the 2.6 kernel and recompile each kernel upgrade.

However I couldn't remember doing that recently.

Using lspci -k.

05:03.0 Serial controller: NetMos Technology PCI 9865 Multi-I/O Controller
Subsystem: Device a000:1000
Kernel driver in use: serial
Kernel modules: parport_pc
05:03.1 Serial controller: NetMos Technology PCI 9865 Multi-I/O Controller
Subsystem: Device a000:1000
Kernel driver in use: serial
Kernel modules: parport_pc
05:03.2 Parallel controller: Illegal Vendor ID Device 9865
Subsystem: Device a000:2000
05:04.0 Serial controller: NetMos Technology PCI 9865 Multi-I/O Controller
Subsystem: Device a000:1000
Kernel driver in use: serial
Kernel modules: parport_pc
05:04.1 Serial controller: NetMos Technology PCI 9865 Multi-I/O Controller
Subsystem: Device a000:1000
Kernel driver in use: serial
Kernel modules: parport_pc
05:04.2 Parallel controller: Illegal Vendor ID Device 9865
Subsystem: Device a000:2000

Looks like the standard drivers work ok. At least up to 115200. If I stty them to 230400 I get

> sudo stty -F /dev/ttyS4 230400
stty: /dev/ttyS4: unable to perform all requested operations

Ummm anyone know how to get higher baud rates out of the standard serial drivers?
