My LX200 GPS has developed severe pointing problems. Although this might not help, I thought it might be a good idea to update the firmware; I've wanted to download updated object info anyway. I connected it using the standard serial port but my computer isn't seeing it. I've read and checked everything I can find. When I look at the port properties in the Device Manager, it says it's enabled and working properly. When I look at renaming the port to a different number, I see that com3 and com4 are already used. My computer's help says that 1 and 3 use the same interrupt and cannot be used at the same time. Could this be the issue? My modem uses com4; I have no idea what uses port 3 or how to determine it so I can turn it off. Any ideas?
Interestingly, when I tried to rename com1 to com2 anyway (which uses the same interrupt as com4), it said it was already opened by an application; I didn't have anything else open though.
I used to know a little about this but it's been a long time; any other way to check the ports? I have a laptop with a serial port, but it's recessed and cannot be used with the Meade cable. I don't have a serial cable to connect the two computers for testing purposes either. I have a Dell PC with Windows XP.
Thanks.
