Digi TransPort WR Routers User Guide 275
DTR de-bounce time s x 20 milliseconds
The length of time (in multiples of 20 ms) for which the DTR signal must be de-asserted before
the router acts on any options that are set to trigger on loss of this signal. Enter the desired
multiple into the text box. Increasing this value makes the router less sensitive to “bouncing” of
the DTR signal. Conversely, decreasing this value makes the router more sensitive. The default of
100ms ( 5 times 20 ms) is a reasonable value.
Escape Character
The character for the escape sequence. The default is the + symbol (ASCII value 43 , 0x2b ).
Changing this value has the same effect as changing the S2 register.
Escape Delay s x 20 milliseconds
The required minimum length of the pause in the escape sequence, in multiples of 20ms. The
default is 50 x 20ms, which means the escape sequence becomes +++ , a pause of 1 second and
then AT, to drop back to AT command mode. If a delay of some other value is required, enter it in
the text box.
Forwarding Timeout s x 10 milliseconds
The length of time that the router will wait for more data after receiving at least one octet of data
through the serial port and transmitting it onwards. This timer is reset each time more data is
received. The router will forward data onwards when either the forwarding timer expires or the
input buffer becomes full. This parameter applies to ADAPT, TCPDIAL, TCPPERM and PANS.
Break Transmit Escape Character c
The character in the escape sequence. The - symbol (ASCII value 45 , 0x2d ) is a recommended
value. Changing this value has the same effect as changing the S3 register. To use the break
sequence, type - three times, with a 1-second pause either side of the three - characters. When
the Async port detects the following sequence, instead of outputting the three minus characters
(they are removed from the output stream), a BREAK condition is placed on the Async
transmitter for 1 second:
<guard time 1 sec>---<guard time 1 sec>
