On the TTL side of couse. It will tell you if you have pulsing when you should not.
Is the MA232 OK. Force the MAX driver (In Software) High and low Look for +/- 12 ( maybe only +/-9). I assume the uP is configured correctly , and you are not sending characters be fore the last on let (checking TI). |
