host. One DMA channel is shared between all the ESP ports. Valid
values are 1 and 3.
-Hayes ESP serial port trigger level
-CONFIG_ESPSERIAL_TRIGGER_LEVEL
- This is the trigger level (in bytes) of the transmit FIFO and the
- receive FIFO. Larger values may result in fewer interrupts;
- however, a value too high could result in data loss. Valid values
- are 1 through 1015.
+Hayes ESP serial port receive trigger level
+CONFIG_ESPSERIAL_RX_TRIGGER
+ This is the trigger level (in bytes) of the receive FIFO. Larger values
+ may result in fewer interrupts; however, a value too high could result in
+ data loss. Valid values are 1 through 1023.

+Hayes ESP serial port transmit trigger level
+CONFIG_ESPSERIAL_TX_TRIGGER
+ This is the trigger level (in bytes) of the transmit FIFO. Larger values
+ may result in fewer interrupts; however, a value too high could result in
+ degraded trasmit performance. Valid values are 1 through 1023.
+
+Hayes ESP serial port flow off level
+CONFIG_ESPSERIAL_FLOW_OFF
+ This is the level (in bytes) at which the ESP port will flow off the remote
+ transmitter. Valid values are 1 through 1023. This value should be greater
+ than the receive trigger level and the flow on level.
+
+Hayes ESP serial port flow on level
+CONFIG_ESPSERIAL_FLOW_ON
+ This is the level (in bytes) at which the ESP port will flow on the remote
+ transmitter after having flowed it off. Valid values are 1 through 1023.
+ This value should be less than the flow off level, but greater than the
+ receive trigger level.
+
+Hayes ESP serial port receiver timeout
+CONFIG_ESPSERIAL_RX_TMOUT
+ This is the amount of time that the ESP port will wait after receiving the
+ final character before signalling an interrupt. Valid values are 0 through
+ 255. A value too high will increase latency, and a value too low will cause
+ unnecessary interrupts.
