Windows Driver
The COM- or LPT-assignments of each port may be changed from the initial values after installing
the drivers. To change the assignment just double-click the entry in the “Advanced” panel.
Figure 12: Port Renaming
Then this panel is opened for renaming a port.
In some cases it may be useful to change the name from COM (or LPT) to something else. Do this
only if you exactly know what you are doing. Usually you will change the number of the first port
only. With the ‘Autoenumerate’ feature enabled the subsequent ports receive the next numbers.
However it is possible to assign port numbers with gaps in between.
3.2.3 Ports Configuration
The available functions of the serial ports depend on the type of UART implemented on the card.
Cards with 16C550A type serial ports provide less configuration than the 16C950 UART. As a
consequence some panels are just missing. This is not a sign of an error.
