[CentOS] is it possible to login to a switch via RS232 / serial port from the shell?

The machine where I use it is still running Centos 4.x - and it looks 
like it has been dropped from 5.x.  If rpmfind doesn't locate a copy, 
the home for the kermit project is http://www.columbia.edu/kermit/ and 
C-kermit would be the version for Linux.
