Alan -- you can find the solution to redirecting COM1 on the Tactical Software knowledge base. Tactical Software provides technical support during your evaluation phase as well as after purchase. Do not hesitate to contact them with question or help.
Here is the entery:
Our redirectors are able to create any virtual COM port from COM1 to COM4096 that is not already defined on the computer. If you are not seeinga certain COM port in the redirector's Select Ports list, it already exists on the PC.
Before our redirectors can create a virtual COM port where there is a real hardware port in the system (such as COM1) the real COM port will need to be removed from the Windows Device Manager and then disabled in the PC's BIOS on system boot.
If you are unsure of what COM ports are in use by the system, you can check the following Windows Registry entry:
HKEY_LOCAL_MACHINE/Hardware/Devicemap/Serialcomm/
Any COM ports with the names starting with DISerial, DESerial, CISerial and SISerial were created with our redirectors.
If you wish to remove any other COM ports that are present, you should find the process/program that created them and remove them with that program. You should not delete any COM ports directly from the registry as that may cause serious system problems.
