Hi, I have tried this with the latest version of GNS3 and it seems to work pretty well, however the console feature does not work, which seems to be because the Simware VMs dont allow console access via COM1, you can connect to the aux port on COM2 but I haven't found a way of getting GNS3 to do that.
This is not a show stopper but it is a bit of a PITA, is there any way to get the Simware VMs to accept console input on COM1?
