[NTLUG:Discuss] communicating with ttyS0

[Fred James]

All
I have  a 'Link12' 1-Wire interface and a AAG 1-Wire interior 
temperature sensor (TA18520).  Now I need to talk to 'ttyS0' from the 
command line (goal is non-interactive scripts - probably 'expect'?)  Can 
you point me to the documentation for communicating with/through 
'ttyS0', please?  Thank you in advance for any help you may be able to 
offer.
Regards
Fred James
