Greetings Using the uart driver from a snapshot of the Denx kernel of about 18 months ago (2.4.22 or thereabouts), I'm trying to sort out the reception of break. The only information I can find that may help identify the code is: BK Id: SCCS/s.uart.c 1.30 11/19/02 11:58:41 trini
The problem I have is that a break doesn't seem to be reported until another character comes along - this means for example that if I get 2 breaks, only one is reported up to the tty layer (I think - maybe a queuing problem at tty level?). The new character is received AFTER the break (so ordering is not a problem). Knowing that there is no really 'standard' SMC driver for 2.4 series kernels I'm not sure if this scenario will ring any bells. If there is a bit I've missed in the interrupt mask (or whatever) that prevents the break being seen, any ideas on what it might be? ie. should I be looking at arch/ppc/8xx_io/uart.c or at drivers/char/n_tty.c !! -- Robin Gilks Senior Design Engineer Phone: (+64)(3) 357 1569 Tait Electronics Fax : (+64)(3) 359 4632 PO Box 1645 Christchurch Email : robin.gilks at tait.co.nz New Zealand ======================================================================= This email, including any attachments, is only for the intended addressee.
