MTPSR1-202ST

Command:

$SBn

Function: Serial Port Speed

Values: n = 3, 12, 24, 48, 96, 192, 384, 576, 1152, 2304, or 4608

Default:

$SB1152

Description: In command mode, the ProxyServer detects the computer’s speed and parity, and

matches it, except when the

%S1

command is active. The

$SBn

command sets the default serial

speed to be used when the TA first powers up. If the TA powers up with $SB460800 set, the TA

powers up in %S1 mode (locked at 460.8 Kbps). If $SBn is set to any other value at power-up, the

TA powers up in %S0 mode (AT auto-detect--maximum auto-detect speed is 230.4 Kbps). Example:

To configure the TA to operate at 460.8K on the serial port at power-up, use the following

initialization string: AT $SB460800 &W0<cr> For clarity, you can add “00” to each command. For

example,

$SB576

and

$SB57600

both set the initial serial port speed to 57,600 bps.

$SB3

Set serial port speed to 300 bps

$SB12

Set serial port speed to 1200 bps

$SB24

Set serial port speed to 2400 bps

$SB48

Set serial port speed to 4800 bps

$SB96

Set serial port speed to 9600 bps

$SB192

Set serial port speed to 19200 bps

$SB384

Set serial port speed to 38400 bps

$SB576

Set serial port speed to 57600 bps

$SB1152

Set serial port speed to 115200 bps

$SB2304

Set serial port speed to 230400 bps

$SB4608

Set serial port speed to 460800 bps

Command:

%Sn

Function: Serial Port Mode

Values: n = 0 or 1

Default:

%S0

Description: Typically, in command mode the ProxyServer selects a serial port speed of 300, 1200,

2400, 4800, 9600, 19200, 38400, 57600, 115200 or 230400 bps, depending on how fast the AT com-

mands are coming from the computer or terminal. Using the

command, you can disable

automatic speed selection and lock the serial port speed to 460800 bps. The serial port speed re-

mains locked until the ProxyServer receives a

%S0

command. Another method for changing from

%S1 to %S0 mode is to send a break at 460.8K. (This method is for cases where the TA was config-

ured on a terminal capable of 460.8K and later moved to a terminal that cannot operate at 460.8K. A

break sent at any speed slower than 460.8K will be interpreted as a break at 460.8K, as will some

characters sent at slower speeds.)

%S0

Automatic speed mode (300-230,400 bps)

%S1

460800 bps mode

Command:

&Kn

Function: Data Compression Mode

Values: n = 0 or 1

Default:

&K0

Description: Enter AT&K1<CR> to enable data compression mode. Since the Hi/fn

algorithm

needs an error correction channel between the compression and decompression processes, it can

only work with error correction competence. V.120 is such a protocol that can be used together with

Hi/fn data compression. Enter AT&K0<CR> to disable Data Compression mode.

&K0

Disable Data Compression mode

&K1

Enable Data Compression mode

* Data compression is not active in X.75 and ML-PPP protocols, but will be in later firmware releases. The compression

ratio for Hi/fn is typically 4:1. If you presently have a Universal Asynchronous Receiver/Transmitter (UART) that is compro-

mising data throughputs, we recommend that it be replaced with a special I/O card.
