Minicom
Minicom is a text-based modem control and terminal emulator program for Unix-like operating systems, originally written by Miquel van Smoorenburg, and modeled after the popular MS-DOS program Telix. Minicom includes a dialing directory, ANSI and VT100 emulation, an scripting language, and other features. Minicom is a menu-driven communications program. It also has an auto ZMODEM download.
A common use for Minicom is when setting up a remote serial console, perhaps as a last resort to access a computer if the LAN is down. This can be done using nothing more than an old 386 laptop with a Minicom floppy distribution such as Pitux or Serial Terminal Linux.
