[AccessD] Serial Communications - Cross Posted VB and Access

Thanks  John,

I did download some code from PSC and it is using mscomm.dll.  I guess I just wondered was there a wrapper for the wrapper.  A heavy duty cardboard box with glossy shiney paper over the plastic bag the product comes in.

I will probably use the mscomm, I was just worried that I will lose some of the data, I am aware enough that I do not know enough about buffers etc to gurantee that it is bullet proof

Thanks anyway,

Mark

  Mark,

  Whenever I need to do serial stuff I use the mscomm.dll that comes with VB.  It "listens" to one comm port, but it also raises events for all the things that need attention.  I then wrap that in my own WithEvents class to do anything specific I need to do.  Other than this Dll I don't know of any brilliant software.  I used to use something called CrystalComm that was a library written in C I believe and provided all of the various functions need to initialize and manipulate the com ports as well as transfer files using the old transfer protocols from the late 80s & early 90s.  Not sure if it is even available anymore.

    Hello All,

    I have to receive serial communications from a scanner and compare it to the data that was just printed.  I have downloaded a few different bits of software from www.planet-source-code.com that all work to a lesser or greater extent.

    Basically, at this stage I can receive data from the serial port.  However, the client is happy to purchase an OCX or some other such tools to enhance the reliability of this project.  There are a few utilities out there for between Euro 100 and Euro 500.  

    The purpose of this email is to ask you guys have you used any such tools or utilities and if so, would you care to pass on the details?

    To state my question again, I can listen to the serial port now, but I just wondered was there some brialliant piece of software that I simply should not ignore.

    As usual,

    thanks in advance for your time and attention,
