I have written an application in Tcl-Expect which spawns minicom and
sends and receives data via the serial port. Sometimes i see that the
application receives control characters along with human readable data.
A search on the internet tells me that the control characters are
nothing but the VT terminal codes. However i could not find a solution
to filter out the terminal codes.
I am attaching a sample of the expected buffer and the actual buffer.

First, to level set: I'm proficient enough with basic BASH scripting for simple things (say, 4 out of 10), but this current project really requires a higher understanding of EXPECT than I have.

dislocate
DISLOCATE(1) General Commands Manual DISLOCATE(1)NAME
Dislocate - disconnect and reconnect processes
SYNOPSIS
dislocate [ program args... ]
INTRODUCTION
Dislocate allows processes to be disconnected and reconnected to the terminal. Possible uses:
o You can disconnect a process from a terminal at work and reconnect from home, to continue working.
o After having your line be dropped due to noise, you can get back to your process without having to restart it from scratch.
o If you have a problem that you would like to show someone, you can set up the scenario at your own terminal, disconnect, walk
down the hall, and reconnect on another terminal.
o If you are in the middle of a great game (or whatever) that does not allow you to save, and someone else kicks you off the ter-
minal, you can disconnect, and reconnect later.
USAGE
When run with no arguments, Dislocate tells you about your disconnected processes and lets you reconnect to one. Otherwise, Dislocate runs
the named program along with any arguments.
By default, ^] is an escape that lets you talk to Dislocate itself. At that point, you can disconnect (by pressing ^D) or suspend Dislo-
cate (by pressing ^Z).
Any Tcl or Expect command is also acceptable at this point. For example, to insert the contents of a the file /etc/motd as if you had
typed it, say:
send -i $out [exec cat /etc/motd]
To send the numbers 1 to 100 in response to the prompt "next #", say:
for {set i 0} {$i<100} {incr i} {
expect -i $in "n"xt #"
send -i $out "$i
}
Scripts can also be prepared and sourced in so that you don't have to type them on the spot.
Dislocate is actually just a simple Expect script. Feel free to make it do what you want it to do or just use Expect directly, without
going through Dislocate. Dislocate understands a few special arguments. These should appear before any program name. Each should be sep-
arated by whitespace. If the arguments themselves takes arguments, these should also be separated by whitespace.
The -escape flag sets the escape to whatever follows. The default escape is ^].
CAVEATS
This program was written by the author as an exercise to show that communicating with disconnected processes is easy. There are many fea-
tures that could be added, but that is not the intent of this program.
