A-9 Using the Termin al Conf igu rat or [software] The [software] section is used to control the receiving and send ing of b ytes over the serial port. Proper setting of these values can significantly enh ance the efficiency of data transmission because the radio is “pack et based” and the UART is “stream based.
Using the Termi nal Con figur ator A-10 transmitted immediately. Conversely, if another character is received before this time-out, th e tim e r is res tarted from the beginning . The rang e for this valu e is from 10 to 65536 millisecond s, th ough it wil l always rou nd up to t he nearest tens o f millisecond s.
A-11 Using the Termin al Conf igu rat or [flow control] The Ethernet Adapter supports the fo llowing six flow control op tions: Recognize RTS, Generate CTS, Recognize DTR, Generate DSR, Recognize XON/XOFF, and Gener ate XON/XOFF. It also supports the original RS-232 specification for flow control where CTS is generated only wh en RTS is asserted.
Using the Termi nal Con figur ator A-12 immediately; other wise, all of the data thereafter would be lo s t.) The host comp uter, however, would have to ask pe rmission fro m the modem to send data. The host wou ld do this by asserting the RTS line. The modem would see this, and check to see if it were ready to accept data.
