12.4 +iTBSN[%] — Telnet Send A Byte Stream
Syntax: AT+iTBSN[%]::
Parameters:
Command Options:
Sends a byte stream of size to the Telnet server.
The exact size of the byte stream that follows.
Telnet Client
A byte stream of size to be sent to the Telnet server.
0..4GB
An 8-bit byte stream of exactly size . If is larger
than 256 bytes, iChip assumes host flow control. Depending
on the setting of the FLW parameter, the flow control mode is
either software or hardware.
Result Code:
Under software flow control mode, the host processor must
respond to iChip‘s flow control characters. The flow control
protocol is detailed in the ―Host iChip Software Flow
Control‖ section later in this document.
Under hardware flow control, the ~CTS/~RTS RS232 control
signals must be connected and the host must respond to
iChip‘s ~CTS signal. The host may send data only when the
~CTS signal is asserted (active low).
% When the auto-flush (‗%‘) flag is specified, the Telnet socket
is automatically flushed immediately after receiving the
from the host. Otherwise, data will be transmitted
to the Internet only in integral quantities of the specified
Maximum Transfer Unit (MTU) or when the AT+iTFSH
command is issued.
I/OK After bytes have been transferred successfully to the
Telnet socket‘s output buffer.
I/ERROR Otherwise
