Serial Diagnostics
Loopback
“
Normal = off
” – no loopback
“
Diagnostics = on
” – helps diagnose COM port issues. While
in loopback mode nothing is sent to the connected device
and nothing is received from the device (Rx and Tx pins
are effectively disconnected from the outside world)
6 . Be
careful when trying to use bidirectional protocols with the
diagnostic mode!
7 [Normal = off]
In most cases, the automatic settings will work perfectly. However, there are a few
exceptions which need to be outlined:
6 If Tx Flow control is enabled, this is still respected and data will not be transmitted if the
connected device is signalling that it is not ok to send.
7 Also, when using this feature, make sure the pass-through socket is in “Stored” or “Not stored”, as
both the “Monitor” and “Debug” modes will dump any data that you try and send to the source.
