[Danny]

Hello fellow forum users.

i have an ekey fsx up e sc with firmware 06180115
Whit licence.

This one worked well and stopped at once.
The leds on de scanner blinks red / green

Code:

require('serial')

port1 = serial.open('/dev/RS485-1', { duplex = 'half' })
port2 = serial.open('/dev/RS485-2', { duplex = 'half' })

function test(p1, p2)
errors = 0

p1:flush()
p2:flush()

for i = 1, 100 do
p1:write('1234567890')
res = p2:read(10, 1)
if res and res == '1234567890' then
res = '+'
else
res = '-'
errors = errors + 1
if errors > 5 then
break
end
end

io.write(res)
io.flush()

if i % 50 == 0 then
print()
end
end
end

test(port2, port1)
test(port1, port2)

alert(errors > 0 and 'ERROR' or 'OK')

Resident script:9: attempt to index local 'p1' (a nil value)
