Enterasys Networks Wireless Ethernet Adapter I manual Using the Terminal Configurator

Using the Terminal Configurator

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.

NOTE

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.
