Indigo is a full-featured telnet and RS232 communications client. Indigo includes many rich features such as data byte converters, session management, syntax/keyword colorization, hotkey macros, split windows, user defined command libraries, and an auto command repeater.
Indigo is an excellent utility for communicating with telnet enabled devices and servers. Indigo is the perfect replacement to Microsoft's Telnet and HyperTerminal client programs. Indigo does not currently support VT100, VT220, VT320, XTERM, SCO-ANSI, or QNX emulation, nor SSH protocols. Indigo is a raw data communications utility.
