Using Mscomm library with Autolisp

Hello,

Has anyone tried to use the mscomm library with autolisp?

This is what I got until now:

(defun loadmscomm ()
(vlax-import-type-library
:tlb-filename "c:\\winnt\\system32\\MSCOMM32.OCX"
:methods-prefix "comm-"
roperties-prefix "comp-"
:constants-prefix "comc-")
)

(defun initcom ()
(setq com1 (vlax-create-object "MSCommLib.MSComm"))
;; use com1
(comp-put-commport com1 "1")
;; 9600 baud, no parity, 8 data, and 1 stop bit
(comp-put-settings com1 "9600,N,8,1")
)

This is the part that will not work: (vlax-create-object
"MSCommLib.MSComm")

Is the string wrong? Do I need to have VB installed on the pc?

The application I would like to implement is to couple a GPS-receiver
to AutoCAD, now using 2004 MAP and LDT.

Thanks,

Bruno

 

I don't see a "(vl-load-com)" call. Have you done that?

If so, open Regedit.exe, and go to HKEY_CLASSES_ROOT. See if you can find a
key whose name is "MSCommLib.MSComm". If the key is not found, it could
mean that MSCOMM.OCX is not registered or present on [your / you user's]
system.

 

If I remember correct it might be a problem with mscomm related to
licensing. Can you get it to work in VB?

Thank you for your response,

It is indeed a problem with licensing. It does not work in VB either.
I get: Run-time error "429": ActiveX component can't create object,
which means that there is no license key on my pc for MSComm.

I am now searching for which product I need to buy to get the license.
I believe VB 6 is no longer available. Is the MSComm library included
in the .net edition? Should I buy a license for every machine where I
want to run my application?

Thanks again for your very helpful response,

Bruno
