any clue why i would be getting this using an EtherLite 162. The ports setup withour error
root@localhost dev]# dinc -8N1s 9600 ttya03
ttya03: Invalid cross-device link
Couldn’t link lockfile name.
[root@localhost dev]#
I’m not sure what would cause that error, but what OS is this? Which driver version?
As far as checking if this is a valid serial port, try the following:
stty -a < /dev/ttya03
If you get good output, at least you’ll know the serial port is valid and troubleshoot this further as a software/application error specific to dinc.
In your example, it looks as though the full path to the device is not entered.
Try:
dinc -8N1s 9600 /dev/ttya03
