Hello everybody,
I want to route COM5 to virtual COM6 to COM8. The HAM-Office software only transfers DTR to control a device connected to the serial interface. DTR is triggered by DSR (software). So far everything works. DTR is triggered. However, monitoring the DSR generates error messages: CNCB4(2) OnCommEvent 9928 [DSR]

Example hub4com instruction:

hub4com.exe --route=ALL:0 --create-filter=pinmap:--dtr=dsr --add-filters=0:pinmap COM2 \.\CNCB3 \.\CNCB4

COM2 Open("COM2", baud=19200, data=8, parity=no, stop=1, octs=on, odsr=off, ox=off, ix=off, idsr=off, ito=0) - OK
CNCB3 Open("\.\CNCB3", baud=19200, data=8, parity=no, stop=1, octs=on, odsr=off, ox=off, ix=off, idsr=off, ito=0) - OK
CNCB4 Open("\.\CNCB4", baud=19200, data=8, parity=no, stop=1, octs=on, odsr=off, ox=off, ix=off, idsr=off, ito=0) - OK
Route data CNCB3(1) --> COM2(0)
Route data CNCB4(2) --> COM2(0)
No route for flow control
Filters:

    \--------------->

COM2(0) |
__/<-{pinmap.OUT}<-

Started COM2(0)
CNCB3(1) Event(s) [DSR] will be monitored
Started CNCB3(1)
CNCB4(2) Event(s) [DSR] will be monitored
Started CNCB4(2)
CNCB4(2) OnCommEvent 9928 [DSR]
CNCB4(2) OnCommEvent 9928 [DSR]
CNCB3(1) OnCommEvent 9928 [DSR]

Question: how and with which options should hub4com be started or how can the error messages be suppressed? ... because in fact everything works fine.

Thanks and best regards
Wolfgang
