ProxyServer User Guide
Command:
$Dn
Function:
Persistent DTR Dialing
Values:
n = 0, or 1
Default:
$D0 (Disabled)
Description:
The $Dn command enables or disables persistent DTR dialing (PDD). PDD causes
the terminal adapter to automatically and continuously redial stored telephone
number 0 when the port has no active calls and DTR is high.
$D0
Disables PDD.
$D1
Enables PDD.
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.

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, 200,
2400, 4800, 9600, 19200, 38400, 57600, 115200 or 230400 bps, depending on how
fast the AT commands are coming from the computer or terminal. Using the %S
command, you can disable automatic speed selection and lock the serial port speed
to 460800 bps. The serial port speed remains 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 configured 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.)
