I just was experimenting a bit with Mod_RSSim Modbus_RS232 and found that when it receives a wrong message (CRC error or too few characters or function code unknown) it never resynchronizes any more, i.e. does not respond until you cycle close-open the com. This happened because my master requires ReportSlave ID. It is not important to my master to get a correct reply; it is important not to hang-up. Normally in Modbus any message is considered terminated after a time-out of at least 3.5 characters. Is there any provision in Mod_RSSim to solve this problem ?
