.Sh BUGS
|
|
Several firmware revisions on
|
|
.Nm
|
|
boards have a terminal emulation bug that shows up when using the
|
|
screen control sequences for inserting blank lines
|
|
near the bottom end of the screen
|
|
(i.e., the control sequences produced by the
|
|
.So al Sc and So AL Sc
|
|
capabilities found in the
|
|
.Xr termcap 5
|
|
database).
|
|
The most likely occasion for triggering
|
|
this bug is to use a full-screen editor such as
|
|
.Xr vi 1
|
|
on the workstation's console.
|
|
.Pp
|
|
To work around this you can set your
|
|
.Ev TERM
|
|
environment variable to the
|
|
.Sq sun-cgsix
|
|
terminal definition which is the same as the
|
|
.Sq sun
|
|
entry, except that the
|
|
.Sq al
|
|
and
|
|
.Sq AL
|
|
capabilities have been removed (at the cost of making the scrolling of
|
|
the screen slower).
