For lack of a better place to post this,
I've recently inherited a dumb terminal with the above nameplate. I assume
the company's name is Ditto (because I'm too lazy to turn the thing over).
My problem is this:  I can't get the thing to go at 2400 baud.  It only
wants to go at 1200.  I have a SupraModem 2400 which is, for all intensive
purposes, a Hayes compatible modem.  I understand it's
necessary to modify the _software_ parameters to change the baud rate.
However, even though I change the SetUp parameters and save them, no 2400.
I'm worried that it might actually be a hardware level setting, in which
case I'll have to get up off me lazy bum and open this thing up.

Any suggestions?

Thank,

Larry
