TALKING TO THE WORLD
PRINTER OUTPUT
DWith the ProDev DDT it is possible to use your printer as an output K
Idevice. This can be done to obtain a hard copy of the screen information K
Ior to allow you to view graphics on the screen while still being able to
debug your program.
JThe printer interface must be in slot #1 and must support the Pascal v1.1 I
Gprotocol. Most printer interface and serial cards should work. See the .
"MO" mode command for selecting printer I/O.
E{DDT16 - When using the IIGS printer port, set the baud rate via the
control panel settings}.
REMOTE TERMINAL
IUsing a remote terminal with the ProDev DDT is also possible. The serial J
Hinterface must be in slot #2 and must support the Pascal v1.1 protocol. K
ISelect the desired baud rate by following the instructions supplied with K
Iyour interface card. If you are using a Super Serial Card or equivalent, F
Duse the switches to set the baud rate & data size. We recommend the ?
following switch settings for 9600 baud operation on the SSC:
sw1 D D D U U U U sw2 U U U U D x D
D{DDT16 - When using the IIGS serial port, set the baud rate via the
control panel settings}.
AThe ProDev DDT does not support error checking. Operation may be K
Iunreliable at very high baud rates. If you experience any communications L
Jproblems, try using the next lowest baud rate. We have found operation at
9600 baud to be very reliable.
GWhen you are operating the ProDev DDT from a terminal you will not see L
Jthe windowed display on the terminal screen. The information displayed to I
Gthe terminal is the same information that would normally appear in the K
Imain display window. The Serial I/O mode is activated from the Mode menu
(See MO command).
JOther computers make great terminals. All you need is a serial interface I
Gand some type of terminal software. Most modem software will work. The I
G][GS even has built in terminal emulation that will work. We prefer to L
Juse modem software that has a scroll back buffer. This allows you to scan L
Jback through instructions that you have already traced in case you missed
something.
JUse the following commands if you want to use the ][GS' built in terminal 4
emulation. From a basic prompt type the following:
] IN #2 <cr>
