CTRLbot Terminator

CTRLbot Terminator is a Windows terminal and network tool for testing connected devices: TCP server and client, Telnet, serial COM ports and SSH in one window, plus local network discovery. MIT licensed.

Features

• TCP Server: listen on any port, accept several clients and broadcast to them.
• Raw TCP (Telnet) Client: send plain text or HEX with a chosen line ending, and turn on Verbose CRLF to see every <CR> and <LF> in the reply.
• Serial (COM): port discovery, baud 9600 to 115200, 7 or 8 data bits, parity and RTS/CTS or Xon/Xoff flow control, with a split TX/RX log.
• SSH Client: password sign-in and an interactive remote shell.
• Scan: finds devices on the selected adapter's IPv4 subnet with ARP, ping and TCP probes, names them from mDNS, SSDP/UPnP and NetBIOS, and looks up manufacturers offline from the bundled IEEE MAC registry.
