Actually my compile result is one less byte of ram compared to the
usb_cdc_line_status() procedure. Of course I am returning a bit
instead of a byte.
function usb_serial_port_is_open'get() return bit is
pragma inline
if cdc_line_status == 0 then
return 0
else
return 1
end if
end function
-- wait till USB device has been connected and serial port has been
opened by the HOST
while !usb_serial_port_is_open loop
usb_serial_flush() -- poll USB at all times
end loop
Matt.
