Thanks for coming back to me Jason

Familiar with cpan etc all good there

Thanks for the heads up on the perl module. 

I will look see what goodies lurk there

I should be able to back to back the two TNCs I have and test them over audio 

Got two pi's and TNCx 

Ok on your LCD I found the same

Yes I assume on Wednesday we can give one Pi a TCP/IP address and the other one as well and use the TNCx boards to ping 

Ax0 is the kiss interface from memory

Need a kiss attach statement

Do you know of a command line ish kiss to Igate software

Set up a simple ISS Igate. 

Can also do it with SDR dongles

I can do perl to Igate that's easy

Will have a go

Cheers 

Andrew
