Distribution is quite capable of controlling the serial ports on VScom cards Driver serial is configured to detect the old fashioned ports known as Com1 to Com4 in DOS systems and support them Since the serial ports on VScom PCI cards use the same type of hardware driver serial is well capable to support the new serial ports After installation of the card the driver serial just needs to know about the new hardware Since Kernel 2 6 things are no longer as simple as written above Some programmers invented a limit to the maximum number of serial ports This is explained below in 5 3 5 1 Manual Installation Usually the command setserial is used to provide the required information to the driver thus adding the port setserial ttys4 port 0x100 irq 5 uart 165504 baud_base 921600 Such a command would be good for an ISA card but with PCI it is not totally as easy as that Because PCI is a Plug amp Play system the parameters port and irq are unknown in advance they are assigned at boot time Depending on your installation of Linux you find the basic parameters in proc pci or via the lspci command Given some hardware details about the card port and irq for each serial port are calculated easy These details are seen in table 14 This is just mentioned here the better way of installation is automatic 5 2 Automatic Installation Depending on your version of the driver serial some VScom PCI card
