You may want to check your USB com port base address and IRQ status.  If they're
not in the "traditional" areas, e.g. COM1 @ 0x3f8 IRQ4, the control packages may
not work.  I've had this problem in the past, both with USB and PCI serial
devices.

It might be possible to force the USB com port settings to something like COM3
or COM4 via Windows' Device Manager.

Has anyone had any luck using a USB -> RS232 converter to control a Pegasus?
I've tried both the TT software and N4PY and they refuse to establish
communications with the Pegasus. If I reconfigure them to use a 'real' COM port,
all works FB.

I've tried connecting the USB -> RS232 converter both to the USB port on the
computer directly and through an externally powered 4 port hub.

The particular converter is a GoldX GXUSB-1200 and I've tried two different
units with the same results.

I also tried hooking up my Rascal computer -> PTT interface to see if the GoldX
converters could control that and that does seem to work. They can control PTT
using either RTS or DTR lines.
