For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.

Hi, Muji, and welcome.

You are very wise to start with a book such as "The Tcl Programming Language".  If you find that book a bit difficult, there are many other books available on Tcl too.  We have a list of 17 books on Tcl and you'll see that I've told you which I recommend on the list.

If you have a question because of something you've read in one of the books, please ask me about it here and I will be happy to answer.  It can take up to 24 hours for me to visit the board and answer questions, so please be patient.  My working life is spent teaching languages such as Tcl and I answer here in my spare time.

I am from China too. I stated learn TCL 3 days ago.

Here I share a piece of script which can be used in RS-232
proc ComSetup {ComPort ComRate} {
  set iChannel [open $ComPort w+]
  set rate $ComRate
  fconfigure $iChannel -mode $ComRate,n,8,1
  fconfigure $iChannel -blocking 0
  fconfigure $iChannel -buffering none
  fileevent $iChannel readable ""
  return $iChannel

proc GetData {iChannel} {
  global output
  after 2000
  set cap [read -nonewline $iChannel]
  return "$cap"  

proc SendCmd {channel command} {
  global output debug

  set letter_delay 10  
  set commandlen [string length $command]
  for {set i 0} {$i < $commandlen} {incr i} {  
     set letter [string index $command $i]
     after $letter_delay
     puts -nonewline $channel $letter
     if {$debug(dutConfig) == 1} {puts -nonewline $output "$letter"}
  after $letter_delay  
  puts -nonewline $channel "\n"
  if {$debug(dutConfig) == 1} {puts $output ""}
  after 500
  flush $channel
