## ◆ SLIP_RX_QUEUE

#define SLIP_RX_QUEUE SLIP_RX_FROM_ISR

Set this to 1 to enable functions to pass in RX bytes from ISR context. If enabled, slipif_received_byte[s]() process incoming bytes and put assembled packets on a queue, which is fed into lwIP from slipif_poll(). If disabled, slipif_poll() polls the serial line (using sio_tryread()). Set this to 1 (default for SLIP_RX_FROM_ISR) to queue incoming packets received by slipif_received_byte[s]() as long as PBUF_POOL pbufs are available. If disabled, packets will be dropped if more than one packet is received.

## ◆ SLIP_USE_RX_THREAD

#define SLIP_USE_RX_THREAD !NO_SYS

Set this to 1 to start a thread that blocks reading on the serial line (using sio_read()).
