Here are the column descriptions:
First == device node number
Second == RS standard (RS-232, RS-485 or TTL)
Third == Header with the pins (COM1 or COM2 header)
Fourth == Tx pin number (& name on schematic)
Fifth == Rx pin number (& name on schematic)
Last == register data for Tx enable (not needed)

Using the first line as an example: Your software would open
/dev/ttz0; your Tx would be on pin #3 of COM2 header and Rx would be
on pin #2 of COM2 header. /dev/ttz1 would have Tx & Rx on pins 7 & 8
of COM1 header, etc.

No, you can still use ttyAM0 while using ttz[0-2], they are independent.
