Has anyone managed to make the vt100 emulation (/usr/bin/async_main)
work without the ua? The manual seems to indicate this is as simple
as:
async_main r path_to_profile:A2 f /dev/tty000
Unfortunately, this seems to block on the open of /dev/tty000 and
is uninteruptible (well, hop over to another window and kill -9 it..., but..).
Some detective work (replacing /usr/bin/async_main with a program that
prints it argc and it's arguments) shows that the ua invokes the thing
as:
async_main r path_to_profile:A2 f /dev/tty000 p 123 i 6
This form is documented (somewhat), but writing a program to do this
invocation after opening the device (with O_NDELAY set) results in
an immediate message "The line has disconnected" (meaning no carrier
was found, which is true).
Argh!!! Has anyone encountered and solved this?
Thanks in advance,
