테스터(vsbtester) buildPacket() 분석 결과:
- 파라미터 있는 명령: 16비트 Big Endian (buildCommandBE)
- 파라미터 없는 명령: 공백 0x20 추가 (buildCommandASCII " ")

변경:
- mpa, mec, msn, mta, mls → buildCommandBE (BE 파라미터)
- mps, maa, mqq, mag, mcj, mid, msp, mbb → buildCommandASCII " " (공백)
- maa sendChannelsOnly도 공백 방식으로 통일 (기존 LE [0] 제거)
