Vector Graphics Mode

After receiving the control code <#777#>GS<#777#> (this can be turned off) or the 4105 command <#778#>ESC<#778#> <#363#><#363#>!0 (ASCII control characters are printed in <#364#>this font<#364#> to distinguish them from printable characters, a space is written <#779#>SP<#779#> ) from the host, UniTerm switches to a separate graphics screen, if the host doesn't send <#780#>ESC<#780#> <#781#>FF<#781#> (the ASCII characters Escape and Formfeed) before starting a new picture, you will have to clear the screen manually with <#782#><#783#>〈<#783#>Alt<#784#>〉<#784#><#785#>〈<#785#>F1<#786#>〉<#786#><#782#> . The incoming characters will be interpreted as Tektronix encoded vectors or commands (see appendix A) until UniTerm receives one of the following codes:

• <#788#>CAN<#788#> will return you to VT102 mode,
• <#789#>ESC<#789#> <#790#>FF<#790#> will clear the screen and enter Tektronix alpha mode.
• <#791#>ESC<#791#> <#375#><#375#>!1 will return to VT102 mode.

To return manually from Tektronix to VT200/VT102/VT100/VT52 mode press <#792#><#793#>〈<#793#>Alt<#794#>〉<#794#><#795#>〈<#795#>F6<#796#>〉<#796#><#792#> or select the appropriate mode from the item Terminal in the menu Settings. To view your picture again press <#798#><#799#>〈<#799#>Alt<#800#>〉<#800#><#801#>〈<#801#>F5<#802#>〉<#802#><#798#> . Be careful, selecting Tektronix 4010 mode manually will also reset the history buffer!
