Right. However, there are two devices, one with a second USB uplink
port, one without. My device is the one without the second USB port.

I tried only the Windows ME driver (Philips98ME2000.zip), found
on the Sitecom's support site at:

Well, as far as I understand this, it could work with an
invalid baudrate setting, because most serial devices (such
as external modems etc) auto adapt to the host's baudrate.
Suppose that the driver is setting the baudrate to 9600 bps,
which means that the driver will be telling the device to set
it at 115200/9600 = 12 = 0x0c. The device will be interpreting this
as being 115200 bps and nobody will notice.
Unless they are using a null modem connection or a fixed baud rate
device (like I was trying to).
I'm positive about my patch (at least for my exact device), I've tested
it at all possible baud rates with a null modem cable.

BTW: Did you see my other patch concerning the maximum packet
