„ nothing is displayed on the screen, the data transmission most be
extremely different from the designated one.
The PC-8201 can transmit graphic characters if the word length is 8
bit (in the same manner where 7 bit length or SI/SO sequence is
used). However, even if the data transmission unit on the other
is not equipped to accept graphics, it will be displayed on t e screen
of the PC-8201 just as if they were being normally transmit e .
With graphics characters in particular, a variety of figures can be
displayed by using the proper device. There are also situations
when a graphics character could be used as a function code,
should pay attention to the type of character set used by
communication equipment at the receiving end.
When the PC-8201 is used as a terminal with mainframe (large
computers), there are instances using the cursor movement keys t
revise the input. What is normally displaved ori the screen o
PC-8201 is what has been input, so determine the PC-8201 cursor
movement code as a single letter in terms o* the mainframe
computer, etc., b.cuase revision cannot be done. Afterwar* <«£"
you do want ,0 revise a letter that has been input, use the Q Key
(character code 8).
