I am using SPC 2.1.4.0 in VB.net 2008. I am trying to communicate with a device that requires RTS and DTR be driven to a low level. I am configuring the serial port to the following
It seems that RTS and DTR are always at a high level no matter how I set the RTS and DTR properties (true or false). I am able to use another application to force RTS and DTR low so it is not my serial port. Any suggestions?
Hello You are using the old version of Serial Port Control. Please use this link to download the latest version (2.1.6) and check if your issue repeats:
I found my problem. Things are working well now with 2.1.4.0. Thanks for your help. One question though. If I wanted to upgrade to the latest version would I be charged full price if I have a license for an older version?
No, an update subscription (that allows you to download newer versions for one year) is a lot cheaper than buying a whole new license. A subscription is $ 199 (as opposed to $699 for a new one).
If you'd like to purchase it, please contact me at george.white@fabulatech.com and I'll give you the purchase link. By the way, in December we are offering discounts!
