Using Serial 3.0.15.
I am using some USB-to-serial adapters on my machine (Win ME), and due to the vagaries of the installation process I ended up with COM1, COM2, and COM4. The serial plugin lists COM1, COM2, and COM3! I was able to rename COM4 to COM3 and get around the problem, but if anyone is maintaining this plugin, this is probably an easy thing to fix.
Now for a problem I have with the behavior of this plugin: occasionally a small alert box pops up with the title "SERIAL" and some error text. I didn't have the presence of mind to write down the exact text, but the problem is, serial events are suspended until I click OK on this alert. Obviously, this isn't going to fly for a home automation computer! Is there a way to defeat this alert dialog?
More details if anyone is interested: the port in question is an RS-485 port. There are 4 other devices on the RS-485 bus: three RCS thermostats and a HomeVision controller. I am trying to use Girder to eliminate the need for the HV. So far, I'm having a lot of success: I've written enough scripting to poll the 'stats and even to change their setpoints. Once I disconnect the HV there will be a LOT less traffic on the bus, and I hope that the serial error alert will be very unlikely. But the fact that it can happen at all is somewhat of a concern, since, as I mentioned, this is an automation PC that is not going to have a human operator in front of it (it won't even have a monitor by the time I'm done with it)!
Any suggestions?
Thanks in advance,
Dave Wagner
