Over-night I was able to experiment a bit with the other uart ports on the debian (102bsp) image:
0) uart0 /dev/ttyS0 console
The uart0 console device has pins on the EXP header; pin(7) and pin(8)
Also, uart0 console device has pins on the euler bus; pin(29) and pin(30)
I used a PL2303 serial ttl cable to each of these ports to veryfiy identical operation.
2) uart2 /dev/ttyS2 PI bus pin(8) and pin(10)
3) uart3 /dev/ttyS3 Euler bus pin(24) and pin(23)
4) uart4 /dev/ttyS4 Euler bus pin(19) and pin(21)
The kernel designations for uart0-4 /dev/ttyS0-4 are affirmed. I used (sudo screen /dev/ttySX 115200) to 'talk' to the serial connection on my HP notebook using the PL2303 serial ttl cable. Rx -- Tx jumper could be used as well.
/dev/ttyS4 is interesting since this uart provides hardware flow control on pin(22) PD5 (CTS) and pin(18) PD4 (RTS).
uart1 is used by the wifi | bt module.
The PineA64 is making a very nice serial controller;
