This uses the 'io' lib instead. Also note the '*a'(readall from buffer) arg passed to infile:read.

Hope this helps  

I think the inFile:read() thing was the problem, as when I changed that, the error changed. I honestly don't know exactly what fixed the problem, but I got it working and cleaned things up a bit! I think it was the read("*a") and requiring io, but I'm not  entirely sure.Thanks a bunch for your help, here's the final product:

local manager = {}

local component = require("component")
local event = require("event")
local io = require("io")

if not component.isAvailable("modem") then
  error("No compatable network card found.")
end

local modem = component.modem
local SENDPORT = 1

function manager.sendFile(fileName, address)
  print("Preparing to send file...")
  modem.open(SENDPORT)
  local inFile = io.open(fileName, 'r')
  local fileString = inFile:read("*a")
  os.sleep(2)
  modem.send(address, SENDPORT, fileName)
  inFile:close()
  print("Sending file...")
  modem.send(address, SENDPORT, fileString)
  modem.close(SENDPORT)
  print("File sent.")
end

-- The library goes on

address is misspelled as 'addresss'. too many s... That was surprisingly hard  

Man, I wish this were the mistake! I don't know how that s got there, but it happened between my source and posting it here, the original code has address spelled correctly. But I'm surprised you caught that, I read over everything after I posted and didn't catch it! I've edited the question so that it's spelled correctly, but the problem still persists.

I'm trying to port over a library I made for Computer Craft, but I can't tell for the life of me where this error is coming from.

I know that the library works properly, as I've gotten another of it's functions working just fine. Sorry if this is a noob question, I am a java developer, and am just getting into lua.
