Who's It For?
moserial is primarily intended for technical users and hardware hackers who need to communicate with embedded systems, test equipment, and serial consoles.
moserial seems to fill a gap in gnomish software.
moserial is intended to fully replace the qt/kde-based cutecom. cutecom is nice, except that its UI is not well thought out - too many clicks are need to start logging, for example. Plus the qt nature of it is out of place in gnome.
moserial also partly replaces the text-based minicom.
gtkterm is another serial terminal for gnome. It mixes the input and output together in a single window (like Hyperterminal), which some users may prefer. It does not support z/x/y modem transfers. The UI is a little unpolished (and not GNOME HIG compliant).
For those migrating from Windows, moserial replaces the handy Hyperlog for Windows (a non-free serial file capture utility), Hyperterminal (the default simple serial app), and Bray Terminal (a hacker's serial terminal).
