Hi,

Me again... I just separated my questions to different threads...

There is strange echo I get by communicating with a pseudo terminal process on MacOSX 10.4 Gambit-Cb14.

I open a dummy process that is a pseudo-terminal using the open-process command and when I send data to the port that data gets repeated in the pseudo-terminal output-port. See the example below for better clarity. Can I turn off that echo?

I cannot test it on the WinXP platform since open-process is not implemented for (MinGW or Cygwin).

Thank you,

Francois Magnan

; Pseudo-terminal program

(define (command-loop)

(let ((command (read-line)))

(serve-command command)

(command-loop)))

(define (serve-command command)

(pp (list "got command" command)))

(command-loop)

; build the above to an executable file called "/tmp/pttest" using gsc and gcc.

---------------------

(define (test-pseudo-terminal)

(let ((port (open-process (list

path: "/tmp/pttest"

stderr-redirection: #t

pseudo-terminal: #t ))))

;(force-output port)

(pp port)

(force-output)

(thread-sleep! 1)

(display "toto\n" port)

(force-output port)

(pp (read-line port))

(close-port port)))

(test-pseudo-terminal)

; execute the above in a gsi interpreter

; On MacOSX 10.4 I get

; "\33[1mtoto\33[m"

;"(\"got command\" \"toto\")"
