When sending a file of between 8160 and 8192 characters, RealTerm will pad the sent file with enough 0x1A (^Z or eof) characters to make 8192 characters. Verify by looping back TX to RX. Sending less or more will not add any 0x1A s. Settings: COM 1, 115200, 8,N,1 no flow control. RealTerm version 2.0.0.70
Please make a sample file for me to test this, and put a link here so I can download it
Indeed the case, still in V3.0.0.26
