[BusyBox] ash : very slow response

[Dinesh Nagpure]

Vladimir,

I just tried using getty from tinylogin-0.80 but now I never get to see any
characters instead system is getting interrupts all the time and LSR is 0x60
(THR empty, THR & TSR empty) and the interrupt handler exits without
transmitting any character because head==tail in the circular queue.

I also tried forcing autoconfig( ) in drivers/char/serial.c to think that
the UART is a 16550, this did set the xmit_fifo_size to 1 but the original
behavior did not change.

I was searching through the archives but could not find a similar issue,
there are a few other init issues discussed though.

Any other clue?

Thanks,
Dinesh

I examined your initial message ("ash very slow"). 
I try to reduce volume of search of a problem. 
Try to switch off the cmdedit and to check up. 

This problem already was sounded in the maillist. 
Init not completely set modes for com ports. 
Still it is possible to try to use getty.
