40 ! This program demonstrates simultaneous FER (receiver sensitivity)
50 ! and rho (transmitter modulation quality) testing. After an FER
60 ! test is started, a softkey interrupt branches program execution
70 ! to a subprogram that queries rho and prints a test result without
80 ! interrupting the FER test.
