  Register 1 Register 1 controls the input of the RS-232 communications port as described in  Table 2 . Table 2    Settings for register 1  Field Description Octal Values BRKINT If BRKINT is set, break is mapped to SIGINTR. On Windows-based systems this field is forced by the system to be set. 000002 = set  000000 = not set ISTRIP If ISTRIP is set, it strips the 8th bit (8th bit is not read). This bit cannot be set on UnMux systems. 000000 = not set IGNCR If IGNCR is set, a received CR character is ignored (not read). 000200 = set  000000 = not set ICRNL If IGNCR is not set and ICRNL is set, a received CR character is translated into a NL character. 000400 = set  000000 = not set INLCR If INLCR is set, a received NL character is translated to a CR character. 000100 = set  000000 = not set IGNBRK If IGNBRK is set, a...

  BT-Basic provides several statements for using the RS-232 ports for communication. These statements enable the system to open and configure a port for RS-232 use. In order to transfer data using RS-232 protocol, an I/O port must be established and configured for RS-232 data transfer. This port is a physical connection to a serial device (such as a printer), from a port on the mux card. A pseudo-device file handles the actual transfer of data to and from the physical device. Thus, when you communicate via RS-232 you are actually accessing a pseudo-device file that the operating system maps to a physical device. Once an RS-232 file is created, the  assign to  statement allows the port (file) to be opened and accessed by the system for data transfer. Then the parameters associated with the RS-232 port are set with one or more  control  statements. The example program shown in  Example 1  demonstrates a data transfer using these statements. Example 1...

  Calling User Functions from BT-Basic If you prefer to control remote instruments from the BT-Basic testplan, see  Example 7 . Although this method produces the same results as  Example 6 , the frequent interaction between BT-Basic and ATL make this a more complex way to do the test. Example 7  has an analog test that uses a high-frequency coaxial port ("FREQ_CNTR_HIGH" and "FREQ_CNTR_LOW") on the module to connect a frequency counter, FREQ_CNTR, to two nodes ("Node1" and "Node2") on the DUT and then make a measurement. The example works as follows: 1    BT-Basic starts the instrument server, calls a user function that sets the frequency counter to a known condition, and executes the analog functional test, "measure1". 2    ATL instructs the ASRU Card to make the connections between the frequency counter and the DUT and then passes control back to BT-Basic. 3    BT-Basic calls a function that makes the measurement, and st...
