•Generates 9900 ill. Arg A:1 T:x ST:xxx if nSer illegal
•Generate 9901 ill. Funct. T:x ST:xxx if serial is not in 485 mode (see ser_mod) |
Example of use:
function SendCommand()
lungh = str_len(StrTx)
ser_bin_out(NUMBER, StrTx, lungh)
FotoTempo = tfb
loopTx:
if((ser_485_tx_sts(NUMSER) r_and 0x31C))
ErroriTx = (ser_485_tx_sts(NUMSER) r_and 0x318)
return
endif
if((tfb - FotoTempo) > 1.0)
ErroriTx = 0x2000
return
endif
goto loopTx
return
