The PCI card EX-41054 from Exsys provides 4 seral ports compatible to RS-232 standard. The card is supported under Linux, however, it depends on the Linux distribution if the four serial ports are initialized automatically or if an additional configuration of the driver is necessary.

The card is available in different version that use different kinds of chipsets. Each version has its own PCI ID (9710:9735, 9710:9745, 9710:9820, 9710:9835, 9710:9845), The ID corresponds to the used chipset: Nm9735CV, Nm9745CV, Nm9820CV, Nm9825CV, Nm9835CV, Nm9845CV, Nm9755CV.

The card can be identified by lspci, or under kernel 2.6 or older by
