Can't open a COM Port. (Solved)
Hi there,
Maybe I am missing something here, but for some reason I can't open a COM port using Flowstone.
Did anyone ever experience this?
I have a USB->UART LCD Module from Sure Electronics connected to my laptop, wich ended up on COM11, but every time I open Flowstone, when I try to connect to the port I first get "Failed to set configuration for port" then it changes to "Com11:Failed" and stays like this every time I try to open it.
If I connect to the module using Putty it works fine, so I guess the COM11 and the module are working fine.
I have tried also a serial adapter on my office's laptop, this time on COM5, same thing.
Also I have a modem on both laptops, both on COM3, same thing.
So either I am doing something wrong or something is broken.
I have searched the forum and I see people also having the same problem, but the conversations usually move towards other subjects and nobody seems to give a direct answer for any of these questions:
1 - Does a COM port higher than COM1 work on Flowstone?
2 - Is there any special configuration to use a COM port higher than COM1?
I am just using the standard 9600-8-n-1 on the COM module, nothing fancy here.
Please let me know if anyone here has had any degree of success on this.
Thanks a lot,
Marcelo.

Re: Can't open a COM Port.
I've used lot's of different com ports with FlowStone with no problems (Com5-Com10). Also different devices, some USB-COM port adapters, some Relay boards with the FTDI chip etc.
One silly thing I did was set the Stop bits wrong as on the Comport module it an Int in so:
0 = 1
1 = 1.5
2 = 2
