Step 2 for computers with MS-Windows: Activate FIFO
If step 1 does not achieve a satisfactory solution to the transmission problem, please
change the following setting in the Windows system.
1.
Open the menu
Start | Control Panel | System | Hardware | Device Manager |
Connections
(COM1, COM2, etc.).
2.
Use the right mouse button to open the popup menu and activate
Properties
.
3.
Go to
Connection settings | Advanced
.
4.
Set the
Receive buffer
and the
Transmit buffer
to
Low (1)
.
5.
Confirm this setting with
OK
.
This Windows setting must be carried out separately for each COM
port (unlike the BIOS setup setting).
Technical background: Depending on the application and settings (XON/XOFF, baud
rate, etc.) it is helpful in case of transmission problems to activate FIFO and to set the
receive buffer or the transmit buffer to
Low (1)
. This causes the buffer to be emptied as
early as possible, so that more time remains if other IRQs require time.
