Page 61: Configuration File Format
Using the Terminal Configurator Configuration File Format The configuration file format is broken down into sections that define a particular grouping of options. Each section contains at the top a section header which is a string of text surrounded by square brackets: [ ] (the section title). After each section header, there is a list of entries containing equal signs. - Page 62 Using the Terminal Configurator [bridge] Bridge provides variables that are common to all radios. Bridge affects the behavior of radios. AP refresh period. Periodically an Ethernet Adapter pings an AP. The AP Refresh Period is the time, in units of seconds, between pings. The default for this value is 60 (which should be left at this default).
- Page 63 Using the Terminal Configurator [software] The [software] section is used to control the receiving and sending of bytes over the serial port. Proper setting of these values can significantly enhance the efficiency of data transmission because the radio is “packet based” and the UART is “stream based.” Stream based data means that the data is transmitted and received one byte at a time, without any mechanism to separate chunks of data from other chunks of data.
- Page 64 Using the Terminal Configurator • input timeout. The Input timeout is how long the Ethernet Adapter will wait after some data has been received on the UART before giving up on waiting for more. Once a character has been received the timer starts with this time- out.
- Page 65 Using the Terminal Configurator [flow control] The Ethernet Adapter supports the following six flow control options: Recognize RTS, Generate CTS, Recognize DTR, Generate DSR, Recognize XON/XOFF, and Generate XON/XOFF. It also supports the original RS-232 specification for flow control where CTS is generated only when RTS is asserted.
- Page 66 Using the Terminal Configurator immediately; otherwise, all of the data thereafter would be lost.) The host computer, however, would have to ask permission from the modem to send data. The host would do this by asserting the RTS line. The modem would see this, and check to see if it were ready to accept data.
- Page 67 Using the Terminal Configurator CTS and DSR are output lines. When set to “negate” or “assert,” they will output a continuous digital value. The value “negate” outputs a logic 1, or “mark” which is electrically negative. This is also the state seen on an RS-232 connector when the cable is unplugged.
