Serial port problem

I am working with solaris 9 sparc and I want to connect physical device in serial port but when I am connecting it,It is showing the error window saying--

Quote:
Warning:The serial port "/dev/term/a" cannot be opened for use.
Please verify that it is entered correctly and that is not already in use.
So can any1 tell me the reason or is there any package I have to add to work with serial port???

NAME
cyclades-devices - tables for driving cyclades-serial-client DESCRIPTION
The cyclades-devices file supplies all mapping between Unix device files (/dev/*) and the addresses of serial ports of Cyclades Terminal Servers. It contains one entry for each serial port, with the following format: device:rastype:rasname:physport:type:options Note: A # character at beginning of line indicates a comment The entry fields are: devname - A full pathname of the file that will be associated to the serial port. It must start with a "/dev/" preffix. Two naming schemes may be used here: - devname does not exist, and will be linked to a free pseudo-tty. This is the default behavior of cyclades-ser- cli. - devname is the name of a valid slave pseudo-tty. In this case, the '-t 1' option must be assigned in options field. (Note: this option is not supported by this release). rastype - Terminal Server type: - prts, for Cyclades Pr302X/TS Terminal Servers. - path, for Cyclades PathRAS Terminal Server. rasname - Host Name or IP Address of the Terminal Server where the serial port resides. physport - Number of physical port in the Terminal Server. If treated as the IP address associated with this port, in a IP-based addressing scheme. type - Server type that will be contacted to handle the serial port: - rtelnet, for Remote Telnet Server - socket, for Socket Server options - Per-port specific options, passed to cyclades-ser-cli program. EXAMPLES
1. Device on a PR3020/TS Terminal Server pr3k Port 1, accessed through /dev/ctty01 device file name, using telnet protocol (remote telnet server) /dev/ctty01:prts:pr3k:1:rtelnet: 2. The same device, but with an IP address pr3k_port1 associated to the serial port (IP-based port addressing) /dev/ctty01:prts:pr3k_port1:0:rtelnet: 3. Device on a PathRAS Terminal Server pr3k Port 2, accessed through /dev/ctty02 device file name, using socket protocol (socket server) /dev/ctty02:path:pr3k:2:socket: FILES
