As a simpler alternative for making a [socket] link with the mathematical manipulation package [maxima],
a valid approach has proven to be to 
[exec] maxima with a [stdin] provided command. The windows maxima distribution appears to have no 
command line version, only the Tk interfaced xmaxima, for which the approach on [Bwise combined with Maxima] 
works for me, which could be improved, but is potentially fairly efficient and flexible.

On this page, I use [Linux], and [BWise] using a recent tcl/tk version from I think [Activestate]. BWise regularly 
requires typing of commands, which is easily done with the console, just for convenience, this is my RedHat 9 
startup script (using a console from [console for Unix]):

 source bwiseprocs0343.tcl

 console eval { wm geom . 80x24+193+335 }

To execute a [Maxima] command, I've made this [proc]edure, primarily for linux/unix:

 proc domaxima {m} {
    set t "display2d:false;\n$m;"
    return [string range [exec maxima << $t | tail -2  ] 4 end-6]
 }

The pipe with tail can certainly be replaced by non-streaming tcl commands, but this appeared to work.

The variable t contains the constructed maxima commands, including setting the format to displaying results in 
reusable form, while the exec is given this variables'  content as stdin. At [EOF] maxima simply quits, and all 
stdout data is flushed and filtered.

Basically calling this procedure will start a maxima process which evaluates the argument m and returns the 
single maxima result, which can also be done as part of a bwise block, of which the blockfunction could be:

   newproc {set Maxima.out [domaxima ${Maxima.in}]} Maxima

This block can now be used in normal bwise graphs, and for instance the right-click popup 'Data' menu 
gives access to its variables, and allows direct editing of the pin variable contents, and allows the 
block to be fired without further graph with the Eval button.

In the same context, I've made a script to automatically use the maxima 'fortran' command to generate function 
values under C control: [a tcl script for function value listing based on a fortran expression].

Also, the xmaxima for linux (unix) can be given a console with the abovementioned script by editing/usr/bin/xmaxima with a text editor, and near the very end adding:

 MAXTkmaxima tkmaxima
 rename exit tkexit
 proc exit {{val "0"}} {tkmaxima exit "" $val}
 
 ## ADD (changing path to match your console script file):
 source /home/theo/Tcl/unixconsole.tcl
 ##
 
 tkmaxima install
