The serial links are all set up to 115200 baud. Dumping out the tty-struct when it hangs shows me this: magic: 0x5401 name: ttyS0 flags: 0x00000A00 count: 1 stopped: 0 hw_stopped: 1 flow_stopped: 0 packet: 0 low_latency: 0 warned: 0 ctrl_status: 0x00 receive_room: 4095 ... It is a little bit strange that always the null modem connection shows this behaviour. May be it's because it has the highest data transfer rate (all other connections are made by isdn modems / 1-channel isdn)? -------- Original-Nachricht -------- > Datum: Tue, 17 Jul 2012 17:38:47 +0100 > Von: Alan Cox <alan@xxxxxxxxxxxxxxxxxxx> > An: "Tobias Arp" <tobiasarp@xxxxxx> > CC: linux-serial@xxxxxxxxxxxxxxx > Betreff: Re: ST16C654 stoppes transmitting after a while > On Tue, 17 Jul 2012 13:36:03 +0200 > "Tobias Arp" <tobiasarp@xxxxxx> wrote: > > > This is a single core arm processor (Cirrus EP9315), could this race > condition happen in this case? > > In theory, otoh it ought to be quite easy to test for. > > How fast are your links - would it be fair to characterise your > environment as a fairly slow CPU handling a lot of fast serial links > > (just trying to understand what the likely places to look might be) > > -- > To unsubscribe from this list: send the line "unsubscribe linux-serial" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
