If one of these variables (in this priority) is set to a locale ending in
|
|
.Ql KOI8-R ,
|
|
characters with the high-order bit set are being interpreted as
|
|
Cyrillic characters. In all other cases, they are being interpreted
|
|
as belonging to the
|
|
.Ql ISO_8859-1
|
|
character set.
|
|
.Sh HISTORY
|
|
Sound support for
|
|
.Nm morse
|
|
added by Lyndon Nerenberg (VE7TCP/VE6BBM) <lyndon@orthanc.com>.
|
|
.Sh BUGS
|
|
Does only understand a few European characters (namely German and
|
|
French), but neither Asian ones, or the continental landline code.
|
|
.Pp
|
|
Sends a bit slower than it should due to system overhead. Some people
|
|
would call this a feature.
