[ts-7000] Re: TS-7260 :How to configure ttyTS0 in B19200, 8 bit, no pairty, 2 stop ?

["fabianhiernaux" <>]

In fact it seems taht the ttyTS0 (COM3) don't support the 2 stop bit 
configuration.

in the tsuart0.c source 
(http://oz.embeddedarm.com/~michael/support/files/tsuart0.c)I can see :

   if (cflag&  CSTOPB) {
     printk("tsuart:unsupported stop bits, using 1\n");
   }


so this config will never work with this port...  :-(


This port is not connected to the cirrus processor but made by TS (into the 
xylinks?)


I'll use the ttyAM1 in place... but I'm not really happy...
