set uart mode <value> sets the UART mode register. This is a bit-mapped value.

0
NOECHO - disables echo of RX data while in
command mode

DATA TRIGGER makes connection on RX data
2
Reserved for future use

UART RX data buffer. See note below for details*

The functioning of bit 4 has changed in ver 2.27 and later of firmware.
Now, when a TCP connection is closed, if there is RX data in the UART
receiver, it if flushed by default.
Enabling this bit using set uart mode 0x10, will hold the uart data in the
buffer until:
1) more chars come in, in which case it will get flushed, or
2) no chars come in and a new connection is made, then the chars
will get forwarded.
set uart tx <0, 1> Disables or enables the TX pin= PIO10 of the UART. Disable will set
PIO10 to an INPUT with weak pulldown.
NOTE: Due to an issue in the UART hardware, the UART does not support even or odd parity.
