A-10
transmitted immediately. Conversely, if another character is received before
this time-out, the timer is restarted from the beginning. The range for this
value is from 10 to 65536 milliseconds, though it will always round up to the
nearest tens of milliseconds. For instance, setting the time-out to 55 will mean
the Ethernet Adapter will wait for 60 milliseconds before giving up and
transmitting the data.
•
delimiters. Delimiters are special characters that specify the end of the
data. Once any of the characters listed in this option are received, the data is
transmitted immediately. In serial communications, there is frequently a
character reserved to mean “end of transmission”. In human-interface
applications, this character is the “newline” or Enter key. For computer to
computer communication, this value may be different. If one exists, adding it
to this list will greatly improve communication efficiency. Up to four
delimiters can be listed here. They are specified as a space separated list of
ASCII values. The values can be written as decimal or hexadecimal numbers.
•
protocol. The data format of the communication between the UART and
radio network is defined by the [protocol]. Possible values are passthrough,
passthrough2, telnet, and LPD.
— Passthrough forwards any data received over the UART or radio
interfaces to the other interface with the data unchanged.
— Passthrough2 operates much like passthrough, but opens a socket in each
direction so that if an Ethernet Adapter loses power, it can re-establish
communications much faster when power returns. Telnet gives a prompt
similar to that of the telnet application found on UNIX systems. Telnet
also interprets the data received over the radio, removing special
character sequences known as “DO” and “DONT” requests.
— LPD is a UNIX print serving protocol. LPD received data in a particular
format over the radio, and converts it into the data stream that should be
sent to the printer. Data sent by the printer is ignored.
When setting up to use LPD, set the printing parameters so that the file is
sent off using the Ethernet Adapter as the remote host. Any remote printer
name can be used so long as it fits within the guidelines for naming a printer.
