As specified in the Language Reference Manual,
Register.Console.Speed is read only. The code you need is as follows:
Code: Select all
Sub Main()
' COM1 is open at the beginning of a program so it needs to be
' closed before changing the baud rate
Call CloseCom(1, 0, 0)
Call OpenCom(1, 9600, Register.RxQueue, Register.TxQueue)
Debug.Print CStr(Register.Console.Speed)
End Sub
I'm not able to test this code right now but it should work.

It is important to note that the "sign on" message will always be output when the speed for Com1 is still at the default speed of 19.2K. If you have a terminal connected that is configured for 9600, the sign on message won't be received correctly. You may suppress the sign on message by placing the directive shown below in the first module listed in your project.
Doing this will set a flag in system Persistent Memory when the code is downloaded. The flag will stay in that state until code is downloaded that specifies that it should be turned on again. See the description of
Option SignOn for more details.
You can also set the flag explicitly in your code as illustrated below. Changing the flag in this manner will not have an effect until the next time the application runs.
Register.SignOn = False
