handshaking. If you are using GilderTerm, all the settings are fixed at the ap-
propriate settings. All you will need to do is select the appropriate ‘COM’
port.
If your terminal emulation program supports VT-52 terminal emulation
(they all do!), you should enable it on the Mp3-50/8 or Mp3-50/40. This will
allow faster screen redraws. You should set your program NOT to insert an
extra LineFeed (LF) character after each Carriage Return (CR) it receives.
You should also tell it NOT to scroll automatically after the eightieth column
is filled. If either of these are on, the screen will be displayed 'double
spaced'. This won't cause any problem, but will make it hard to see the
whole screen at one time.
If you have hooked up the Mp3-50/8 or Mp3-50/40 to your computer
and it still doesn't seem to respond to the keyboard, the first thing to check
is that you are attached to the right serial port. The easiest way to do this is
to disconnect the Mp3-50/8 or Mp3-50/40 and short between the Tx data
out and Rx data in pins on the serial port connector on the back of your
computer. On all IBMs and compatibles this means sticking a piece of wire,
paper clip, or similar tool between pins 2 and 3 on the 'Com.' connector.
While still running the modem program, anything you type should be shown
on the screen while this paper clip is in place, while nothing will appear
when you remove it. If your computer passes this test, then you are using
the right serial port and the problem is most likely the baud rate setting or in
your wiring to the Mp3-50/8 or Mp3-50/40. If you get characters on the
screen even with the paper clip removed from the serial port, it means you
probably need to set the 'echo' mode to 'none' or 'full duplex' and try this
test again.
To enter the configuration mode you need to type the following. The
(address) is replaced by the ‘Serial Address’ set in the Mp3 Configurator
program:
m5AA5(Card Address)
If any other card is in configuration mode (or even if it just thinks anoth-
er card is in configuration), the Mp3-50/8 or Mp3-50/40 won't be able to
enter configuration mode. To exit any other card from configuration type
'XN'. You can then try entering configuration again.
When you enter configuration the Mp3-50/8 or Mp3-50/40 will display
the following screen if no shows are loaded:
