Does the included terminal software support sending a SysRq break signal to the remote console (if it's a rs232 linux tty)?

It transmits data in binary, so if the bits go in one end, they come out the other. This works even to the point of passing RS485 multidrop addresses. Since SysRq is just a key sequence represented by a binary sequence, as long as your source device doesn't intercept it, it will come out at the remote RS232 interface.

I’d like to control a remote projector that only has an Rs232 port. Can each device be given a static ip?

Each device be given a static ip,but this product is a data transmission device. If you want to control a remote projector,we recommend the USR-IO424T-EWR.

is the serial port modbus compatable?

it support transparent modbus data.do not support modbus RTU to modbus TCP. pls refer model USR-TCP232-410s which support modbus RTU to modbus TCP.
