Connecting with Telnet

  Related Topics

You can initiate a Telnet connection attempt from within Procomm Plus in one of three ways:

•	By double clicking a Telnet entry or group in the Connection Directory, or by highlighting the entry and clicking on Connect.

•	By selecting a Telnet entry from the Rapid Connect list.

•	By selecting Manual Connection from the Connection Directory and supplying a Telnet address.

Whether you select an entry from the Connection Directory or manually connect, you will need the address of the specific Telnet host.

For step-by-step instructions on creating a complete Telnet entry in the Connection Directory, see Adding a Telnet-class Entry.

The following topics describe the Telnet support within Procomm Plus. These topics include  instructions on how to add a Telnet connection,and  how to add a Telnet entry to your Connection Directory.

 A Telnet connection provides point-to-point terminal communications over TCP/IP networks. Typically, these connections are made with either VT-102 or ANSI-BBS terminal emulation. Depending on the host, file transfers are also possible using Zmodem or Kermit.

Alternate Terminal Names

When Telnet negotiates a connection, the host system typically requests your terminal type. By default, Procomm Plus sends the name of the terminal you’re using during the connection - for example, for VT-100, Procomm Plus sends vt100. However, some host systems will not recognize this exact terminal name; instead, they might require the string "dec-vt100".

You can specify the string to be sent for any Telnet entry in your Connection Directory; display the Telnet Options group in the directory for that entry and type the required string in the field When negotiating the Telnet terminal type...

UNIX termcap tables

On UNIX systems, terminal emulation sequences are handled through the termcaps table; unfortunately, these tables are often wrong or incomplete. If you encounter problems with function keys or arrow keys while using Telnet with a UNIX host, check with the host system administrator to see if the termcap file is set up correctly on the host.

File Transfers through Telnet

Although FTP is preferred for file transfers, you can use Telnet if necessary. However, note that many UNIX machines reserve or process control characters, and this will interfere with a transfer. Under such circumstances, use the KERMIT protocol in binary transfer mode. If you encounter problems when using Zmodem to transfer a file to or from a UNIX or VMS host, make sure you add the "-e" switch to the Zmodem protocol command line you type on the host.


Telnet and the Terminal Window

  Related Topics

Functionally, the Telnet window operates almost identically to the standard Procomm Plus Terminal window.

Most Telnet host systems require the VT-102 terminal emualtion; however, if you're connecting to a PC-based BBS via Telnet, you should be able to use ANSI-BBS to take advantage of ANSI graphics and color if the BBS supports it.

For more information on the Action Bar and menu system available within the Telnet window, see The Terminal Window Menus and Action Bar.

Procomm Plus provides Telnet functionality over both serial and network connections. To use the Telnet support in Procomm Plus, you must install a Windows Sockets-compliant WINSOCK TCP stack provider.

Before you can successfully connect to a Telnet host, you must have an Internet or network connection. You can either make a dial-up connection with an Internet Service Provider or connect using network equipment, but this link must be preconfigured before you attempt to connect to a Telnet host.
