It’s recommended to specify the data type prior to writing data to a file with WRF. If ASCII (IPA) is selected, then each character is changed to its ASCII value and sent to the file – RED text is sent to the VNC1L or VNC2 monitor: IPA<CR> D:\> OPW TEST.TXT<CR> D:\> WRF 4<CR> TESTD:\> CLF TEST.TXT<CR> D:\>. When HEX (IPH) input values are used, then hex values are sent, usually with the short command set (SCS). Note that the number of bytes specified with WRF (0x08) is a double-word (4-bytes): IPH<CR> D:\> SCS<CR> D:\> 09 20 54 45 53 54 2E 54 53 53 0D 3E 08 20 00 00 00 04 0D 54 45 53 54 3E 0A 20 54 45 53 54 2E 54 53 53 0D 3E. When testing command sequences with a terminal program, select one that can send hex values directly, such as CoolTerm (http://freeware.the-meiers.org/#CoolTerm).
