how to Send data to Serial port (COM1) through DLLs without mscomm.ocx

I guess there isn't another way of doing this, without using MSCOMM.

If "VB DLL" you mean an ActiveX DLL project without forms, then I would add a (dummy) form to the project, only used as a container for the MSCOMM object.

This form could be set as not visible (also at design time), and your DLL will continue working without an user interface.

Hope this helps

Try

Shell("print /d:com1 file.dat")

Where file.dat contains data you want to send via COM1.

Hi emadat:
Can i Read/Write to a comm port with Single Open Stmt?

Yes you can.
Nothing should prevent you from doing that.

but How? Can u please send a code for the same..

I realise this has been closed for a while now but for the record, another way of accessing the serial port via VB or VBA is to use Cheapcomm, a freeware OCX that does all the basic functions of MSCOMM.

I've used this successfully on a few projects.
