    Those are the ones, Tim. You can also order these in printed form, if you like.

    Lance,
    Are the manuals you are speaking of the 2 supplied in PDF format
    or are there others as well?

    The books that come with PB/DOS are pretty comprehensive. Suggesting other reading material is a little difficult without knowing your "level of skill". IOW, for complete newbies to programming, the Learning Basic book by Don Inman is a good start, but the supplied manuals should cover much the same ground (and more!).

    Personally, I recommend reading through the manuals a couple of times - that helped me a LOT.

    Next, try studying some of the code supplied with PB/DOS, and what has posted on these forums here (and in the Source Code forum, and SRCCODE archive forum), PLUS what you can find in the downloads section at http://www.powerbasic.com/files/pub/pbdos

    Other good sites for information and source code can be found in the LINK section at http://www.powerbasic.com/support/links/ and at http://www.basicguru.com

    I hope this helps!

    Tom,

    Thanks for the direction. I am from the land of VB and so some of this is new/different
    for me. Obviously you had to *see* it somewhere to *know* to use those command sets.

    Any good books you could recommend to help familiarize myself with this form of basic?

    Thanks
    Tim

    This is not done by individual PowerBASIC commands, but by the process
    we like to refer to as "programming". Please see the example code in the
    COMMUNIT.BAS file that comes with PB/DOS.

    Lance,

    Thanks for your response to my question. For one final one, I have printed
    out both PDF files and have gone through them fairly extensively
    to gain a general understanging of PB and see what built in commands are avaialble.
    I do not recall seeing anywhere these options to clear, set high low etc.
    Can you give me an aproximate location in either manual where I
    would find this?

    Thanks
    Tim

    You simply need to set/clear bit 1 (zero based) of the UART's modem control register (set=RTS LOW, clear=RTS HIGH). It should be possible for you to adapt some of the COMMUNIT.BAS code that comes with PB/DOS 3.5 to this task...

    The OPEN COM section describes how to open with certain params set. What I am looking to do is to
    turn the RTS line on or off without opening and closing the com continuously.

    Also, I see many references to the PB Communications library. What is the name of the
    file? I have downloaded several that *might* be it but not certain.

    Thanks
    Tim

    Check out the OPEN COM section of the reference guide.
    That pretty much explains everything.

    Controlling RTS and other IO

    Is there any sample code that demonstrates how to turn RTS on and Off
    and how to use other IO?
