Type
Function returning Byte
Invocation
Console.Read()
Discussion
This function can be invoked to retrieve a character from the input queue associated with Com1 (by
default, but see Option Console in the ZBasic Language Reference Manual). If the value of
Register.Console.Echo is True, the character will automatically be sent back out via the output
queue associated with the designated serial channel. When this function is called it will not return until a
character is available. However, other tasks will continue to execute. You may wish to query the
designated queue to find out if there are characters available before calling this function. See the
example below.
Example
Dim b as Byte
b = Console.Read() ' this will wait until a character is available
If (GetQueueCount(CByteArray(Register.RxQueue)) > 0) Then
b = Console.Read() ' read the next available character
End If
Compatibility
This function is not available in BasicX compatibility mode.
