TERMINAL EMULATION 

GRAPHICS SELECTION

Third party clients do not always handle graphic characters and commands as expected. The Georgia SoftWorks Windows NT/2000 Telnet Server is flexible in providing options for handling graphic characters with 3^rd party clients. If you are unsure of which graphics mode to select the typical progression is the order that the selections are presented. The first works for all, the next is more specialized and so on. Feel free to experiment to determine the best graphics mode for your 3^rd party client. The graphics mode prompt indicates the recommended selection when SCO Console emulation is selected.

Replace PC graphics characters with star characters:

This simply replaces PC graphics characters with the "asterisk" character,

Translate PC Graphics characters:

For VT emulation's the system converts the PC Graphic Characters to ACS and will temporally invoke Special Graphics character sets[8]. PC Graphics without ACS equivalents will be converted to the "asterisk" character.

SCO Console special handling (recommended)

For SCO Console the system will inject appropriate escape sequences to display the graphic characters.

Pass PC Graphics characters without changes:.

This will pass any chars >= 0x80 without any changes.

Pass all characters from PC Screen without changes:.

This will pass all characters from the NT/2000 screen; your client software may have trouble with handling ASCII values for some of control characters like 0x08 (backspace).

Georgia SoftWorks MSDOS Client:

This is used when using the unsupported Georgia SoftWorks modified CUTCP/CUTE (NCSA) utilities for MSDOS.. See web page http://www.georgiasoftworks.com/othertools.htm for more details.

If you do not want to be prompted for the graphics mode each time you log on using a 3^rd party client the you may set an environment variable on a per user basis using Logon Scripting. The environment variable for the graphics mode is:

            gwtn_graphics

For example to select star graphics character substitution you would enter:

            set gwtn_graphics=0

in the Logon Script for a particular user.

NOTE: No spaces are allowed when setting environment variables. For example:

                        set gwtn_graphics=2 is correct

                        set gwtn_graphics = 2 is not correct
