@JonW; I saw it and still do not understand why the PCS PIM serial port is unique?
Here only have a 9 pin serial SA PIM so its probably not work playing with if the PCS PIM is different.
Did a bit of virtual serial port diagnostic testing with the HAI PIM plugged into the Quatech server and me accessing the box in my home office.

Takes 5 minutes to set this up. I have an LED RS-232 9 pin tester but cannot find it this morning. I used this stuff when I configured my GPS/PPS serial cable for my NTP server running on PFSense. The serial cable is around 75 feet from the basement to the attic GPS. It is a custom serial port / cable connection as the PPS signal is on the DCD pin.
I used it again to split my Davis weather station console to two such that I could test two weather applications. (didn't work though). It does work with an Upstart to PIM connection.
I use a couple of old GPS programs. You can see relating to the HAI serial PM DSR/CTS LEDs are always on.
Change the file extensions from PDF to ZIP then unzip.
1 - download and run XPort. XPort is a virtual serial port splitter. Note that connection is at 4800 baud. Ignore the GPS messages.
XPort download.
2 - download and run View attachment SerialPortLEDs.pdf on second serial port configured.
3 - connect Upstart to first serial port configured.
Watch the virtual LEDs.
