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

MacWise Version 12.05
Displays Pictures

MacWise can now display pictures.
The pictures can reside on the Mac or a server.
Windows PC drives on the network are also supported for storing pictures.
Pictures can be placed anywhere on the screen under host control.
They can also be sized and scaled to specific dimensions or can retain their original aspect ratio. Accuterm escape sequences are supported for displaying pictures.

Picture formats supported include:
jpeg, tiff, png, gif, jp2, pict, bmp, qtif, psd, pdf, sgi, and tga

Displaying Pictures

If your host is already programmed to display pictures using Accuterm escape sequences, you may not have to change the host programming at all. Just mount the network drive containing your pictures on your Mac using the Finder's Go Menu. (See "MOUNTING A WINDOWS PC DRIVE TO ACCESS YOUR PICTURES").

If you want to do some host programming to display pictures, follow these guidelines:

ESC STX iL , filename , col , row , width , height , aspect, border CR

Displays the image file, "filename" at column "col" and row "row".
Columns and rows are based upon character positions (not pixels).
Height and width are optional; if specified (and not zero), the image is scaled to "height" rows and "width" columns. Otherwise, the original image size is used.
If aspect is non- zero, the image aspect ratio is preserved (the specified width or height is reduced to preserve the aspect ratio).
Border is
N for no border,
B for simple border,
R for raised border or
I for inset border style.

Note: MacWise only supports the B (simple) border.

Images are considered “protected” data.
A “clear un-protected characters” command will not clear images from the terminal

To maintain compatibility with PC's on the network, it is best to use DOS file name paths in your host programming. Then the same programming will work for PC's running Accuterm and Macs runing MacWise.

DOS file names use backslashes to separate folders.
For instance your path might look like C:\MyPicturefolder\MyPicture.jpg

You can also access a Windows PC over the network to retrieve your pictures.
Click on the Desktop and then select "Connect to Server" from the Go Menu.
Then use an smb path to mount the PC server.
Then the PC drive "PCDriveName" will be mounted on your Mac Desktop.
When you display a picture from the PC drive on the network, you would use a pathname like this:

File names must be complete paths.
You can use Mac filename paths such as VolumeName:MyPicturefolder:MyPicture.jpg
(where VolumeName is the name of the drive).
Mac path names use colons to separate folders.
Pictures can be on your Mac or on a network drive.
If you use "BootVolume" as the Volume Name, MacWise will automatically use the name of your Mac drive.

ESC STX iD , filename CR
Removes the displayed image file filename from the screen.

Clears all displayed images from the screen.


MacWise allows a Macintosh to be used as a terminal -- connected to a host computer directly, by modem, local area network or over the Internet. The emulators support video attributes such as dim, reverse, underline, 132-column modes, protected fields and graphic characters sent from the host computer, as well as enhanced Viewpoint mode. Features include phone list and dialer for modems, on-screen programmable function keys, connection scripts and more.


MacWise emulates ADDS Viewpoint, Wyse 50, Wyse 60, Wyse 370, Televideo TV 925, DEC VT100, VT220 and Prism terminals. Supports ANSI color. Esprit III color is also supported in Wyse 370 mode. SCO ANSI is also supported.

If your office uses a business computer that allows you to log in as a terminal, you can use MacWise to access your business data from your Macintosh when you are out of the office (or in the office).

MacWise will connect your Mac to the office computer using your modem or with ethernet using a LAN connection in your office or over the Internet.
