I can log in at RS232 port using Hyperterminal, sometimes the characters I type for Login: will register, ...sometimes not.
The only speed that works [sometimes] is 19200, other speeds result in return display of strange characters. Often times the characters I type will not appear.
When I do manage to progress to the 1st Options box, the numbers I type do not appear and are not received upon hitting ENTER, nothing happens.

Any ideas are appreciated
