Re: PuTTY telnet not opening.
David J Taylor
Thanks for you comments.
I hadn't changed the two leads connecting the SR1 to the PC - Control to a USB port and Management to
an Ethernet port.
Same ports for several years.
I clicked 'something' in the PuTTY programme settings which has caused the problem.
I have 2 PuTTY desktop icons - PuTTY SR1 telnet and PuTTY SR1 USB.
If I recall correctly the USB one opened as a black screen and you had to type in a 0 (zero)
or 0 enter and the programme started.
That I have tried configuring it for COM1 - it opens with a black screen - type in a 0 (0 appears) but nothing
happens. press enter, nothing happens except green curser moves down.
You can type telnet, which appears, but nothing happens.
Press enter and the green cursed moves down a line.
The telnet short cut always opened as a black scree with telnet and password below.
The password being telnet.
Both worked OK (IIRC) but the USB one ceased ages ago meaning I used the telnet one.
Looking at the EUMETSAT SR1 setup guide again - 'higher up' - I think I've found the answer?
You will see from the attached Device Manager image that DM does not include:
Silicon Labs CP210x USB to UART Bridge (COM3) in the Ports list.
If I recall correctly it did many years ago.
So where is it?
And is that the problem?
It's been so long since I used the serial that I can't be sure, but I think that the port will only show it the device is plugged in and working. There may also be an issue with drivers - you may need to re-install the original Silicon Labs drivers you had. Perhaps on the disk which came with the Ayecka?
But if the Telnet works, why not use it?
