A quick skim of the code suggests your note on the port used by the pps_gen_parport module is correct - the parallel port used by the module will be the first within the kernel's list of registered parallel ports. #HYPACK MAX DOWNLOAD SERIAL#
I shall walk you through the process of setting up a serial port and hyperterminal on a computer running win…
USB Type-C: is a standardized USB connector benefits include the compact, sleek, and reversible design. USB Power Delivery increases the power capability of USB to 100 W and is particularly useful when SIM interface board: serial port B, serial port A, 1 PPS BNC 1 PPS Output waveforms The Trimble Palisade is a self-contained GPS antenna and receiver which generates a UTC synchronized 1 PPS output, automatically performing cold-start and auto-survey as necessary. 
Dtoverlay=pps-gpio,gpiopin=18 # Listen for the GPS PPS signal on gpio18. Plug a null modem crossover cable from a console terminal or laptop into the device serial port. It is a digital bit transmitted every second with a pulse width of 10 milliseconds.

The RasPi leaves out the serial control lines, which is why you had to use the GPIO pin, and why there is no obvious conenction between the USB0 and the pps0, unless you tell gpsd how to make that connection.

As for the module behaviour control, I went with adding 2 parameters to pps-ldisc: - activepin (charp) wich can be dcd (default) or cts and drives the pin which should be consider to detect the 1PPS signal - invertlogic (bool) which can be false (default) or true and defines if the driver complies with a RS232 type signal where assert is on the 1000 PPS 100 PPS 1 PPM 0 PPS 1 PPS: 1st Digit: Form Designation: 0 1: One serial port Can generate interrupts PCI Time Code Receiver and Generator Up to 32 serial devices of any type can be connected to the NPort® 6000, using the same IP address. In low pin count devices (6 to 20 pins), the PPS module allows a digital signal to be routed to any pin, with no limitations.
PPS sinks will now use what are termed Request Data Objects (RDOs) to make these real-time dynamic adjustments to power. 00 *Also compatible with Alpha Elegant/Elegant Dual and Alpha Legend + Products Using the default sentence settings and baud rate, I got an average of 348 bytes/s, which with a baud rate of 9600 (9600 bits/second) would take 290 milliseconds to send. Ethernet port, standard for Internet/Intranet coms. In the past, to communicate with a Serial Port using. When I use the external pps sites to give the time to the nearest second (starting PPS with /etc/init. You should have a position lock very quickly. The serial port that is providing the serial data will be a serial port that has group "dialout". 
PPS Troubleshooting To use the PPS signal from a GPS for time sync you must use a HYPACK PPS box interfaced between the GPS and you computer serial port. The final step is to modify /etc/pps-client.
The PPS-API based on draft-mogul-pps-api-05. Here are the basic read functions: (there are several other, but these are the simplest and will work for most applications) int readChar() - returns the next char from the input buffer int readByte() – returns the next byte from the input buffer string readLine() – returns Cables for a variety of ways to make the physical connection from PC to router using homemade or commercial USB-serial and serial-serial cables.
