Menu Commands → Quick Connection

Note: There are various Quick Start Guides also offer descriptions of this dialog. They are tailored to the use of specific communication methods (SSH, telnet, serial, etc.) while the text below is a general overview.


Quick Connection is a dialog which lets you quickly set up a connection to a host. It is intended for connections which you do not plan to make on a regular basis. For hosts to which you connect often, you should instead add an entry to the Host Directory. Host directory entries can then be activated through various shortcut methods (e.g. user buttons or key combinations) and they offer a variety of other benefits, e.g. automatic login.


To make a quick connection, you need to select a connection type, the host to connect to, an optional port number (for telnet, rlogin and SSH connections), an emulation and your login data (for SSH and Rlogin connections).

Connect to

Depending on the connection type, you can enter a host name or IP address, a phone number or whatever identifies the remote host.

This field offers also list of recently made connections. If you want to reconnect to a host to which you recently made a connection, simply pick the host from the drop down list.

Connection Type Specific Considerations for the Connect-To Field

Local Shell (macOS only)

For Local Shell you can use either localhost or Alternately enter the name of a shell to run in the ZOC window in shebang format, e.g. #!/bin/bash

Telnet, Rlogin or SSH

If the Telnet, Rlogin or SSH is selected for communication (see Connection type below), you will also be able to enter an ip port (e.g. 110 to connect to a pop3 server or a custom port number if your host requires it). Leaving the field empty will use the default ports for the respective method (e.g. 22 for SSH or 23 for telnet).


If you want to connect to a router or device which is directly attached to the serial port, there are two alternatives:

1. In the Connect to field or type localhost or serial. Then click the Configure button for Serial/Direct and select your serial port and communication parameters.
2. In the Connect to field enter the name of the communication port (e.g. COM2 under Windows or /dev/cu.pl2303serial on macOS), then click the Configure button for Serial/Direct, set your parameters, but leave the port field in the configuration dialog empty.


If you connect through Serial/Modem, you will be offered to choose a Dial-Command. These commands refer to the AT-commands in the Serial/Modem options (click 'Configure' next to Serial/Modem, the edit the serial parameters and AT-Commands). The AT commands will be sent to the attached modem to make the actual connection.

Session profile

If necessary, you can make the connection based on a session profile different from the one which is currently loaded. However, in any case (loaded or current), the selection of connection type and emulation in the quick connect window will override the corresponding settings from the session profile. This allows you to use a session profile which matches your needs generally (in regard to screen layout, f-keys, etc.) and reuse it for connections that require different connection types and emulations.

Connection type

This is a list of connection types which can be used to make the connection. Most of these methods can be configured by clicking the Configure button next to the list. Alternately, general defaults for each communication type can be set in the Device section of the Session Profile.


Here you select a terminal emulation which will be used to let the host display data in the terminal area of ZOC. The emulation will depend on your remote host. For connections to Linux or Unix hosts the Xterm or VT220 emulations will be a good choices, although other systems sometimes require quite specific and even obscure choices. Emulation specific settings can be configured by clicking the Configure button next to the list and general defaults can be defined for each emulation in Options→Session Profile→Emulation.


SSH and Rlogin communication will offer a field to enter your username. Type a username or use the text %USERNAME% or %USERNAMELWR% or %USERNAMEUPR% to log in using the same username that was used to log on to your workstation (the latter two placeholders are variants of the username translated to lower or upper case characters). This field will be used to identify you on the remote host. If you enter ? as a username here, you will be prompted for one at login time.


SSH will also offer a field to enter your password. The password is usually required together with your username and you will be prompted for one if you do not enter it here.

If you enable the Save password option, ZOC will remember the password if you use this dialog again for the same host (you can manage saved passwords in Options→Program Settings→Passwords).

SSH key

When making SSH connections, some hosts require files containing public and private encryption keys rather than using a username/password pair for identification. You can either pick an individual file from the SSH directory (configured in Options-Menu, Program Settings, Folders) or use the global SSH authentication file, which are chosen by pressing the configure button next to where you select Secure Shell in this window or through the secure shell settings in Edit Session Profile→Connection Type

If, instead of a private key file, you provide the full name and path of a PKCS#11 compatible DLL, ZOC will use that pkcs11 DLL to access your smart-card and retrieve the identy from the SmartCard chip.

Note: Public/private key file pairs can be created through the Manage SSH Keys function, which is available from ZOC's File menu while Secure Shell is your active communication method.
