I have tried to communicate to modem with the IO library but without success, maybe something is wrong, it would be possible with some code like this I attach?
I prefer this first method but if itsn't possible how I should use the luaX?
---------
local file="/dev/ttyS1"
local r
local function write_read(fd,cmd)
fd:write(cmd)
fd:flush()
print("write: ",cmd)
r = fd:read() --read default mode
print("read: ",r)
end
local fd=assert(io.open(file,"rw"))
fd:flush()
fd:setvbuf("no")
write_read(fd,"at\r")
fd:close()

An external library is needed. LuaX, by Asko Kauppi, had one I think.
