[comp.periphs] Help with Teletype Model 43

steve@gec-mi-at.co.uk (Steve Lademann) (06/19/87)

We're having some problems with a Model 43 Teletype which we have recently
acquired, minus its manual. Now, I don't even know if it's RS232 - does anyone
know how to tell? Also, the 'alarm' light seems to be permanentlty lit, no
matter what we do - is there something we're not doing (like looping some pins
on the interface) ?

Anticipatory Thanks

 Its been along time since i used a TTY43. There was several reasons the 
alarm light would be on. But the one that was the most frequent was:

    - There is a switch under the cover which detects if the top is open.
      Most of the problem i had was with that  switch. All is did was
      to put some tape over it.
   
If there is a problem with the status on the RS232 interface the terminal
will stay in local mode and not go online.
