i.chnl[#].src.com - Source COM Serial
| ID | Type | Example | Description |
|---|---|---|---|
i.chnl[#].src.com.autobauding |
integer | 0 |
Whether the serial port is autobauding. 0=no, 1=yes. |
i.chnl[#].src.com.autobaudrate |
integer | 0 |
The baud rate detected during the autobauding phase. |
i.chnl[#].src.com.cts |
integer | 0 |
The live state of the CTS input line. 0=unasserted, 1=asserted. |
i.chnl[#].src.com.detect |
string | '0000' |
The diagnostics information for the COM port. Normally '222x', '333x', or '0000'. #Firmware/v270 |
i.chnl[#].src.com.dsr |
integer | 0 |
The state of the DSR input line. 0=unasserted, 1=asserted. |
i.chnl[#].src.com.dtr |
integer | 1 |
The current state of the DTR output line. 0=unasserted, 1=asserted. |
i.chnl[#].src.com.pdce |
integer | 0 |
Internal debugging information. Shows the total number of times the serial input buffer has been exhausted (and so data would have been lost). |
i.chnl[#].src.com.pdcne |
integer | 0 |
Internal debugging information. Shows the total number of times the serial input buffer has nearly been exhausted (so the ip.buffer has had to signal “stop sending” with the Rx Flow handshake lines). |
i.chnl[#].src.com.protocol |
string | '8N' |
The current protocol being used. Changes during autobauding (and indicates the current protocol that is being tested). |
i.chnl[#].src.com.rts |
integer | 1 |
The current state of the RTS output line. 0=unasserted, 1=asserted. |
i.chnl[#].src.com.rxpin |
string | '3' |
The receive pin that the serial port is using. See #COM Port rxpin |
rxpin| Value | Description |
|---|---|
0 |
not connected |
2 |
DTE |
3 |
DCE |
2* |
DTE but receive data also detected on pin 3 as well. ie. Y-lead situation. |
When autobauding completes, the baud rate and protocol are programmed into the
c.chnl[#].src.com values so the ip.buffer can reboot with the correct settings.
