RELATED TOPIC

We are working to have WL2K packet stations (ham-to-internet e-mail) set up
as "BBS" type nodes on the FPAC network. We are also alpha testing SMS
(Small Message System) direct from packet to WL2K internet server through
the FPAC network (to the nearest FPAC switch that has 24/7 intent
connection.)

The WL2K connection supports the Airmail E-mail client (terminal program) or
conventional NEXUS ham to email and also runs on HF 24/7.  The SMS system
would be for keyboarding directly into the WL2K CMBO/Server in Cleveland to
keyboard in SP or e-mail  messages or pick up (RM) messages.  The SMS system
leads to having palm-pilot-level computers and small packet radios/tncs in
tactical opns keyboarding directly into the internet-based WL2K ham-to-email
system.  Eventually SMS should be able to take uploaded file transfers as
well as keyboard sending.

Along with this we have discussed asking Tom to provide FPAC source code to
the WL2K development team.  I am not sure John WB4MOZ has sent that request
to Tom yet.
