MacWise - Macintosh Terminal Emulation - telnet / serial for OS X - Wyse, Viewpoint, VT100, VT220

MacWise Terminal Emulation for Macintosh
Version 10.9.10 Released
with support for Kermit

May 29th 2007

MacWise can now use Kermit to log into your host using telnet or secure shell. If your host sends files to your Mac using the Kermit file transfer protocol, MacWise will automatically receive the file and place it in the kermit_Transfers folder in your Documents folder.

Kermit File Transfers

Select Kermit from the Connection Menu in MacWise, to enable Kermit file transfers.
Close the MacWise connection and re-open it. You will automatically log in using Kermit.
MacWise supports Kermit for telnet, ssh secure shell and Mac Unix Shell connections.

If the host sends a file to you using the Kermit file transfer protocol, the file will be transferred
to your kermit_transfers folder in your documents folder

The nice thing about Kermit file transfers is that files are received automatically with no operator intervention.
Just look in your kermit_transfers folder for any files transferred.
NOTE: Files with the same name will be overwritten.
Kermit automatically names the file ft.txt if it is a text file.
Each time you do a transfer from the host to your Mac, you will need to move or rename the existing file if you do not want it to be overwritten with the new file transfer.

If you need to send a file to the host, you will need to connect using the Mac Unix Shell.
Then type ? to get help with the Kermit commands.
For instance if you wanted to send a file to the host using telnet from the Mac Unix Shell, you would tyoe:
telnet YourHostIPAddress (where YourHostIpAddress is the IP address of the host you are connecting to. then type...
send YourFile (where YourFile is the name of a file in the kermit_transfers folder.

NOTE: If you get a Warning message during the file transfer stating that your terminal type is not recognized, you will need to change the terminal type that you have entered into the Telnet Connection... window under the Connection Menu. If Kermit does not recognize your terminal type, it will close your connection and exit into the unix shell the second time you do a kermit transfer.
Standard terminal types to use are:

Emulation TERM type
Prism prism7
TV925 tvi925
VT100 vt100
VT220 vt220
Viewpoint viewpoint
Wyse 50 wy50
Wyse 60 wy60
Wyse 370 wy370

If you are using anything other than vt100, vt220 or wy50, you will need to install extra terminfo files on your Mac.
Please read the file called "terminfo installation instuctions.rtf" located in your MacWise folder.
Also, read the file, "Kermit File Transfers.rtf" in your MacWise folder.

Kermit Installation Instructions

Kermit Installation is optional
If your host requires Kermit file transfers, then read the following instructions for installing Kermit.

Download Kermit from Mac Update at
The file you download will have a rather cryptic name such as
This is not an installer file. (Do not double click on the file)
Rename this file to kermit (all lower case).
Then drag the kermit file into the kermit folder.
The kermit folder is in your user library folder. ( User/library/kermit )
To locate this folder, open any finder window and click on your home icon. Then open the library folder and look for the kermit folder.

That's it. Now, put a check mark on Kermit under the MacWise Connection Menu and the next time you log into your host, you will be connected using Kermit.

1. You can verify that kermit is working by opening a connection to the Mac unix shell. Your prompt should say C-Kermit>

2. If the download link for Kermit changes in the future, just go to and do a search for C-Kermit

3. If you have kermit working with MacWise on one Mac and would like to transfer it to another Mac, just copy the kermit folder from the working mac to the other mac.

4. You can get the latest beta version of Kermit source code and compile it yourself if you wish.
The daily source code is at
click on the http version to download.
It is easy to compile the source code. Just read the makefile.
It will tell you the make command to use. For instance,
make macosx10.4 is the command for OS X 10.4.9
It creates a file called wermit.
Just rename it to kermit and put it in your user/library/kermit folder.

Bug fixes in MacWise 10.9.10...

Fix - If the host tells MacWise to open your browser to a http address longer than 256 characters, it will now work. Previous versions would just send an error message back to the host if the address was too long. MacWise will open your browser to a specified address when it receives "ESC Control B < theHTTPaddress" from the host.

Fix - Added a warning dialog box if you are doing a Kermit file transfer with Accuterm commands and your term type is not recognized by Kermit.
(Kermit will fail on the second data transfer if it does not recognize your term type entered in the telnet connection window or ssh.
MacWise now provides installation instructions for terminfo files needed by Kermit.

Fix - Control ] was only working in Viewpoint mode but not VT100 or Wyse

Fix - Telnet or ssh connection was exiting to the Kermit prompt. Changed so it now clears the screen and closes the connection to the Mac shell when the host closes the connection.

Fix - MacWise will now make sure that the kermit binary is an executable file each time it opens a unix connection with kermit.
