Interesting things Ive found with this, thought someone on the list might
eventually have a similar problem to what I had, so here is the fix:
(Interestingly enough this was _NOT_ nessasary under jail)
In screen's config.h the following exists:
/*
* If your system has the new format /etc/ttys (like 4.3 BSD) and the
* getttyent(3) library functions, define GETTTYENT.
*/
#define GETTTYENT 1
if you change that to #define GETTTYENT 0 (I.E you undefine the option) it
works 100% and will give you all your new terminals.
As a matter of interest, if anyone here can explain to me why this fixed
my problem, or perhaps let me know if there is a problem with
getttyent() under jail it would be much appreciated.
Thanks
Andrew Alston
