orkiman

solved. kratmel thanks! i use the mj20-rs rs232 communication module. the problem was i didn't cross rx and tx in the d-sub. maybe I had to cross it because I use a weird usb-to-rs232 with female end instead of the regular mail d-sub at the end. and " check connection via info mode... " is a good advice anyway this code is working 😀

hi try to read RS232 data with JZ20-J-R16 I send the data : <0x2>12345678<0x3> 9600,8,1,N but SB won't turn ON. no matter what.. can someone help ? the documentation is poor.. attached my program : betsalelMatch.U90
