Telnet, serial & raw TCP

Beyond SSH, TermZ connects to the gear that doesn’t speak it.

Telnet

For legacy devices and console servers. Telnet is unencrypted, and TermZ flags that clearly in the connect form so the choice is deliberate. Default port is 23.

Serial

Console-cable access to switches, routers, and embedded devices. Pick the serial port, then set the line parameters to match the device:

Setting	Typical values
Baud rate	9600, 19200, 115200, …
Parity	none / even / odd
Stop bits	1 or 2

Raw TCP

Open a bare socket to any host and port — terminal servers, custom services, or anything that speaks plain bytes over TCP.

Caution

Telnet and raw sockets have no encryption or server identity. Anything you type, including credentials, crosses the network in the clear, and there’s no way to verify the far end. Use them only on trusted networks.
