Linux communication programs

[gt7030a at prism.gatech.edu (gt7030a at prism.gatech.edu)]

Currently I am still using my dos communications program (through a 
modem) and I would like to find a relatively easy to use Linux
program.  Anyone have any suggestions.  Ftp sites would be helpful also,
even though it will probably be either sunsite or ftp.cc.gatech.edu 
where it is found :)

Thanks.
