Hi Ken & All,
Think g__day is correct with the Ascom & Lx200 setting.
Bear in mind that serial ports can only accept 1 connection until the "hub" in Ascom loads.
Windows device manager can sometimes change port assignments. Pay to check.
Also, increase the default port speed to 57600. This allows the buffers to clear at a faster rate.
It can also send delayed adjustments if the "pc" is busy, this can be
frustrating.
Praying for clear skies...
