Pq sun4c/sun4m 48.Cd "cgsix0 at obio0 addr 0xfb000000 level 4" Pq sun4/300 49.Cd "cgsix0 at obio0 addr 0x0b000000 level 4" Pq sun4/100 50.Sh DESCRIPTION 51The 52.Nm cgsix 53is a memory based color frame buffer. 54It supports the minimal ioctl's needed to run 55.Xr X 1 . 56.Sh SEE ALSO 57.Xr bwtwo 4 , 58.Xr cgtwo 4 , 59.Xr cgthree 4 , 60.Xr cgfour 4 , 61.Xr cgeight 4 , 62.Xr tcx 4 63.Sh BUGS 64Several firmware revisions on 65.Nm 66boards have a terminal emulation bug that shows up when using the 67screen control sequences for inserting blank lines 68near the bottom end of the screen 69(i.e., the control sequences produced by the 70.So al Sc and So AL Sc 71capabilities found in the 72.Xr termcap 5 73database). 74The most likely occasion for triggering 75this bug is to use a full-screen editor such as 76.Xr vi 1 77on the workstation's console. 78.Pp 79To work around this you can set your 80.Ev TERM 81environment variable to the 82.Sq sun-cgsix 83terminal definition which is the same as the 84.Sq sun 85entry, except that the 86.Sq al 87and 88.Sq AL 89capabilities have been removed (at the cost of making the scrolling of 90the screen slower). 91
