Expect slowing down / missing characters
Im writing an expect program to connect to cisco routers and run commands.
my commands file has only two entries
Code:
show version
show running-config

when I run the script, the first command is run without a problem.
The second command isn't.
The "s" is missing at the device command line, the "h" is the only character at the command line. The script pauses for a few seconds, then moves on to the exit line in the script.

this is what it looks like


Code:
cisco WS-C3750-48P (PowerPC405) processor (revision J0) with 118784K/12280K bytes of memory.
Processor board ID CAT0936Z4SZ
Last reset from power-on
Target IOS Version 12.2(25)SEE
4 Virtual Ethernet interfaces
48 FastEthernet interfaces
4 Gigabit Ethernet interfaces

Router#how running
              ^
% Invalid input detected at '^' marker.

and heres my code


Code:
set cmdlist [open "listofcmds" "r" ]
while { [gets $cmdlist command] >=0 } {
send "$command\n"
sleep 10
expect "#"
                }

send "exit\n"

thks in advance for help

ppmtosixel

ppmtosixel(1)						      General Commands Manual						     ppmtosixel(1)

NAME

       ppmtosixel - convert a portable pixmap into DEC sixel format

SYNOPSIS

       ppmtosixel [-raw] [-margin] [ppmfile]

DESCRIPTION

       Reads  a  portable  pixmap  as input.  Produces sixel commands (SIX) as output.	The output is formatted for color printing, e.g. for a DEC
       LJ250 color inkjet printer.

       If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled.  A printer control header and a color assignment table
       begin the SIX file.  Image data is written in a compressed format by default.  A printer control footer ends the image file.

OPTIONS

       -raw   If  specified,  each  pixel  will  be explicitly described in the image file.  If -raw is not specified, output will default to com-
	      pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands.  A raw file is often an order	of  magni-
	      tude larger than a compressed file and prints much slower.

       -margin
	      If  -margin  is not specified, the image will be start at the left margin (of the window, paper, or whatever).  If -margin is speci-
	      fied, a 1.5 inch left margin will offset the image.

PRINTING

       Generally, sixel files must reach the printer unfiltered.  Use the lpr -x option or cat filename > /dev/tty0?.

BUGS

       Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion.  If the original PPM maxval was
       greater	than  100,  rescaling  also reduces the image depth.  While the actual RGB values from the ppm file are more or less retained, the
       color palette of the LJ250 may not match the colors on your screen.  This seems to be a printer limitation.
