This function reads the TSP-Link trigger lines as a digital I/O port.
Type TSP-Link accessible
Function Yes
Usage

Details
The binary equivalent of the returned value indicates the input pattern on the I/O port. The least
significant bit of the binary number corresponds to line 1 and the value of bit 3 corresponds to line 3.
For example, a returned value of 2 has a binary equivalent of 010. This indicates that line 2 is high
(1), and that the other two lines are low (0).
Example
data = tsplink.readport()
print(data)
Reads state of all three TSP-Link lines.
Assuming line 2 is set high, the output is:
2.000000e+00
(binary 010)
The format of the output may vary depending on the ASCII precision setting.
