Enabling Telnet Client in Windows 7

A Telnet Client enables connectivity to a remote machine via the Telnet protocol. By default, Telnet over Windows 7 is not enabled, however it is easy to enable Telnet by following the steps outlined on http://social.technet.microsoft.com/wiki/contents/articles/910.windows-7-enabling-telnet-client.aspx

  • Select Use TN3270 Protocol to work with TELNET SNA extensions.
  • Specify the LU Name of the host (LU name or LU pool).
TN5250TELNET for 5250 emulations

Defining Print Parameters

As a Telnet client, PowerTerm InterConnect enables the user to define print parameters in order to print the terminal screen or data transferred from the host application. PowerTerm InterConnect supports a few different methods of printing host information to local or network-accessible printer resources.

In most cases, the user does not have to modify the standard printer stream before sending it to a defined printer. Printing can be done in either Text or Graphic mode. For IBM 5250 printing emulations there is also the option to enable Host Transform printing.

Keyboard Mapping

PowerTerm Telnet Client enables the user to map PC keys to host keys in order to emulate the host terminal keyboard. The keyboard mapping definitions are stored in a file with the same name as the current terminal setup file, with the extension .ptk. For example, the default keyboard mapping definitions are stored as ptdef.ptk.

The Keyboard Mapping dialog is presented in three colors:

  • Gray, is a virtual (terminal) key
  • White, is an OS character
  • Yellow, is an OS dead character

The PowerTerm Telnet Client enables users to save keyboard-mapping settings separately as well as customize the keyboard to emit a certain sound when certain actions are taken, automatically repeat a certain behavior and to perform many other tasks.

PSL Scripts

Ericom PowerTerm Script Language (PSL) is a full-featured programming language, which enables the Telnet user to create scripts for automating tasks. For example, a PSL script can be created for automatic login. Scripts can be used when PowerTerm starts up, when connecting via Telnet to a session or can be utilized any time during a PowerTerm Telnet session.
