About the SPEED serial adaptor card
The SPEED product range are high performance, serial adaptor cards for PCI based host
machines. Each card features four RJ45 ports, removing the need for spider or octopus
cables. You can use up to four cards per host thus providing 16 ports per host.
The SPEED4 variant supports a full compliment of eight signal lines per port. The
includes enhanced modem support and significantly higher maximum port speeds.
Each serial port has three device nodes associated with it. Each node takes the form of a
special file which you can access in the normal manner from operating system utilities and
user applications. See also Appendix A Serial port device names and your operating
system manual for details of special files .

an existing computer system rather than replacing it with the considerable cost that entails.
Higher data rates and ESD protection in the make it suitable for any modem or
ISDN TA application.
