Dear all,
Trying to do things better and listen to some advices... I am going to create a new Thread.
I'm trying to connect a PC shell serial emulator (putty) to the COM2 connector of the TS 7880 board and I don't success. I have checked all the configuration parameters and the mailing list mesages, tried all I have thought and it is like COM2 doesn't exist!!! I copy some chekings I have done:
ls -l /dev
-rw-r--r-- 1 root root 5 Sep 1 02:26 ttAM1
-rw-r--r-- 1 root root 5 Sep 1 02:26 ttAm1 crw-rw-rw- 1 root tty 5, 0 Feb 18 2009 tty crw------- 1 root tty 4, 0 Aug 31 03:43 tty0 crw------- 1 root root 4, 1 Sep 1 01:07 tty1 crw------- 1 root root 4, 2 Sep 1 01:07 tty2 crw------- 1 root root 4, 3 Sep 1 01:07 tty3 crw------- 1 root root 4, 4 Sep 1 01:07 tty4 crw------- 1 root root 4, 5 Sep 1 01:07 tty5 crw------- 1 root root 4, 6 Sep 1 01:07 tty6 crw------- 1 root tty 4, 7 Feb 18 2009 tty7 crw------- 1 root tty 4, 8 Sep 1 02:58 tty8 crw------- 1 root tty 4, 9 Feb 18 2009 tty9 crwxr-xr-x 1 root root 204, 16 Mar 16 2006 ttyAM0 -rw-r--r-- 1 root root 5 Sep 1 02:35 ttyAM1 -rw-r--r-- 1 root root 5 Sep 1 02:35 ttyAS1 crw------- 1 root tty 4, 64 Sep 1 03:17 ttyS0 -rwxrwxrwx 1 root root 34 Sep 1 02:58 ttyS1 So it seems ttyS1 ie COM2 exists....
ps aux
root 715 0.0 0.9 2948 1208 ttyS0 Ss 03:08 0:00 /bin/login --
root 716 0.0 1.2 2956 1544 ttyS0 S 03:08 0:00 -bash www-data 720 0.0 1.6 14228 2064 ? S 03:08 0:00 /usr/sbin/apach www-data 721 0.0 1.9 235648 2528 ?

Sl 03:08 0:00 /usr/sbin/apach root 786 0.0 0.7 2476 936 ttyS0 R+ 03:19 0:00 ps aux So it seems that console is in ttyS0 ie COM1 nano /etc/inittab #1:2345:respawn: /sbin/getty 38400 tty1
#2:23:respawn: /sbin/getty 38400 tty2 #3:23:respawn: /sbin/getty 38400 tty3 #4:23:respawn: /sbin/getty 38400 tty4 #5:23:respawn: /sbin/getty 38400 tty5 #6:23:respawn: /sbin/getty 38400 tty6 T0:23:respawn: /sbin/getty -L ttyS0 115200 vt100
#T1:23:respawn: /sbin/getty -L ttyS1 115200 vt100 So it seems that console is in ttyS0 and ttyS1 is free!!
If I do: ts7800:~# echo hola > /dev/ttyS0 It prints hola in ttyS0 (just where I am ie my shell serial emulator) so it seems that ttyS0 is console.
If I do:
ts7800:~# echo hola > /dev/ttyS1
ts7800:~# echo hola > /dev/ttyAM1 ts7800:~# echo hola > /dev/ttyAS1 nothing!!!!
ts7800:~# echo hola > /dev/ttyAM0
-bash: /dev/ttyAM0: No such device or address It doesn't exist... As you can see it is like COM2 doesn't exist!!!!
I have checked serial bus cable and it is ok.... (red line just on the board dot) I am using TS manufactured cable.... so....
I am lost..... I have no more ideas....
Would you be so gratefull to help me with this??? thanks!!
PD: Sorry for my bad english __._,_.___
