[U-Boot] DUTS: missing pieces for a beginner

Dear Niklaus,

I think this is easily possible. Detlev and Vitaly have been working
heavily on DUTS in the past months, and I can imagine they did not
always update the documentation.

Detlev, maybe you can comment here?

Again, this is better for Detlev to comment...

Cool - thank in advance. Detlev, say yes, and quickly :-)

"connect" is a small shell script we use internally:

===============================================================================
#!/bin/bash

if [ $# != 1 ] ; then
	echo "Usage: $0 target" >&2
	exit 1
fi

CMD=''

case "$1" in

-l|-h|--help|-?)
	echo 'Known targets:'
	while read srv trg prt
	do
		[ "$trg" ] && echo $trg
	done <<_E_O_F_ | \
	pr -o 4 -t -5 -w76
$LIST

	exit 0
	;;

*)	while read srv trg port
	do
		tmp1=`echo $trg | tr '[:upper:]' '[:lower:]'`
		tmp2=`echo  $1  | tr '[:upper:]' '[:lower:]'`
		if [ "$tmp1" = "$tmp2" ]
		then 
			TRG=$trg
			if [ -z "$port" ]
			then
				CMD="/usr/bin/rlogin $srv -l $trg"
			else
				CMD="/usr/bin/telnet $srv $port"
			fi
		fi
	done <<_E_O_F_
$LIST
_E_O_F_
	;;
esac

if [ -z "$CMD" ]
then
	echo "Unknown target: $1" >&2
	exit 1
fi
echo "### Connect to \"$TRG\" using command: $CMD"
exec $CMD
=========================================================================

We are using two types of terminal servers here: one type (for
example Lantronix ETS types, or Linux boxen with multiport serial
cards running our "tserver" package, see
ftp://ftp.denx.de/pub/tools/tserver-0.17-4.src.rpm) can be connected
using a "rlogin server_name port_name" command, while the other type
(for example Cyclades TS2000 / TS3000) require a "telnet server_name
port_number" command).

In your setup you could use our connect script, and install the
"tserver" package on your host system; then use an entry like

	# port  device          parameters
	#
	sequoia	/dev/ttyUSB3	115200,8,N,1

in  your  /etc/tserver.conf  file  -  then  you  can  use  a  "rlogin
server_name  sequoia"  command  to  attach  to  this port which works
nicely with the above tools.

Best regards,

Wolfgang Denk
