NOTE:
1. Transmission data must be in ASCII code.
2. Delimit the data from the controller with CR or CR and LF. Query data and the GPIB delimiters are the same.
Therefore, send DLO or DL3 after serial port was opened (refer to the example of RS-232 remote program).
Data transmission example: Personal computers can recognize both CF 30.0MZ CR and CF 30.0MZ CR
LF.
The format for query data is +3.00000000000E+07 CR LF (send DLO or DL3). The output data of this RS-
232 and GPIB are the same number of characters except delimiters (CR and LF).
