4 Windows Driver

Enhanced Software Settings

Figure 19: Software Settings

This is a special feature of the VScom driver. In older driver versions it was simply called Over-

speed.

Overspeed opens the possibility to get other speeds than the application requested for. The appli-

cation requests a certain speed; this is multiplied with the value deﬁned in here. The result is set

as the real speed. Possible factors range from 0.125 (1 divided by 8) up to 32 in steps of 0.125. Of

course you can not get a speed which is higher than the maximum speed of the port (921600 bps /

3.6 Mbps). The normal value is 1 of course, and it should be left there. This is a feature with some

risk. With a modem you very easy get a speed the modem can not handle.

Examples:

• Wrong: Overspeed is set to 8. The modem has a maximum interface rate of 460800 Baud.

When the application requests 115200, the result is 921600 Baud. The modem can not handle

this.
