A92: Receiving an ASCII-romdump with Serial link and TclTk


Some time ago I joined the technical science course of our school, and 
we're now learning TclTk. Last weekend I figured out, how you can 
receive an ASCII romdump through the serial port (Graph Link cable)
with a TclTk script or directly from the console (Wish). 

You'll have to do something like this:

## change this value, if necessary #
set Port "com2"

set src [open com2 r]
set dst [open "ti92.rom" w]
fconfigure $src -mode 9600,n,8,1 -blocking 0 -buffering none
-translation binary

proc Read {} {
    global src dst
    set r [read $src]
    if {[string compare $src ""]} {
        after 100 Read
    }
    puts -nonewline $dst $r
}

I hope this will help someone.
