string pszVerifyInput;
try {
// Note: Example uses the WaveLinkTerminal object to dynamically position the screen output.
ioIface.RFPrint(0, 0, "WaveLink Corporation", WaveLinkIO.WLCLEAR | WaveLinkIO.WLREVERSE);
ioIface.RFPrint(0, 1, " Auto Detailing ", WaveLinkIO.WLNORMAL);
ioIface.RFPrint(0, (termIface.TerminalHeight() – 1), " Press any key ", WaveLinkIO.WLNORMAL);
// Flush the output buffer and await keystroke/scan.
pszVerifyInput = ioIface.GetEvent();
}
catch (WaveLinkError wlErr) {
