Mike, I don't believe the software has any option for saving a serial port selection. At least I have never found one. It defaults to COM1. I use a USB/RS-232 converter and COM 2 because COM 1 on my laptop is in use by another application. I have to select COM2 every time I start the program. I don't do it that often so it is only a minor annoyance.
As for why it only works on COM 4 on your PC, I would need a bit more information but I can speculate. Does your PC have the older RS-232 or newer USB serial ports? If you have the former, then the Trimble is connected to COM4. If you are using USB ports and a USB/RS-232 adapter (s) then the adapter has assumed the COM4 identifier when it was plugged into the USB port. When a USB/RS-232 adapter is plugged into a USB port it assumes a COMn identifier, usually the next available one. You may find that the system has already defined COM1, COM2, and COM3. This can happen if you move a USB/RS-232 adapter to a different USB port or have several adapters. In the following steps I am assuming you are using a Windows PC running XP and have USB ports and are using a USB/RS-232 adapter(s). If so go to Control Panel and open the System folder. Click on the Hardware tab. On the Hardware page click the Device Manager button. Click on the "+" sign next to Ports (COM & LPT). You will see a list of COM ports defined on your system. If you don't see COM1 defined in the list then you COULD change the COM4 port to COM1. Here is how. Right click the COM4 entry. Click Properties. Click Port Settings. Click Advanced. Find the COM Port Number: pull down box. You should see COM4 in the box. Click the down arrow and select COM1. Click OK. Click OK until you are back to the Device Manager screen where you started. You should see COM1 listed as one of the ports. It may be necessary to close and reopen the Device Manager to see the change. Good luck.
