If necessary, set the DIP switches.
Install the RocketPort Jet in the PC.
After boot-up, log in as supervisor or use su as shown below:
[test@lnx test]$ su

Check the PCI device status. The following illustrates a RocketPort Jet 4-port installation.
[root@lnx test]# lspci -v
...

If output of the lspci -v shows something similar to above system
response, the RocketPort Jet card has been correctly detected
by the system.
Set the port for the correct clock speed by configuring the baud_base,
for example:
setserial /dev/ttyS4 baud_base 921600
setserial /dev/ttyS5 baud_base 921600
To set the baud base when the system boots, place the setserial baud_base
command in the following files where applicable:
Ubuntu and Debian derivatives /etc/rc.local
Redhat and derivatives /etc/rc.local
SuSe /etc/init.d/boot.local
Gentoo /etc/conf.d/local.start
Verify the available serial ports that reside in the system:
[root@lnx test]# more /proc/tty/driver/serial
