Working in Conversational Mode
In conversational mode, all characters you enter at the keyboard are immediately sent to the remote
host. The characters are not displayed on the screen until the remote host echoes them back. The
only exceptions are a few control codes that affect the display but are not transmitted to the host.
Display memory is organized as one continuous page of 300 display lines, 24 of which appear
at one time. You can scroll the displayed text up and down one line or one page at a time.
Characters you enter or characters received from the host are displayed at the current cursor
position. If you scroll, you may write over existing characters unless you return to the last line of
text.
To speed up the display in conversational mode, line 25 is displayed on line 3 of the screen and
may scroll off your screen.

In conversational mode, keys that invoke the following functions are ignored:

Working in Block Mode
In block mode, the emulator transmits and receives data in blocks, and the host controls the format
of each page and which page is displayed on the screen. You can type in several lines (up to a
full screen) and edit the data before it is transmitted.
Block mode has two submodes: protect and nonprotect:
•
Protect submode allows the host application to designate specific areas of the screen as
protected; for example, a screen form might have protected and unprotected fields. The cursor
skips over the protected areas.
•
Nonprotect submode does not allow the designation of protected areas and is used by
applications such as editing programs that allow you to determine the format of the data you
enter. You can move the cursor to any position on the screen (except the status line) and enter
any type of characters, depending on the data attributes the application defines for the field.
The application can define an unprotected field with the following attributes:
◦
Free entry—You can enter any type of character.
◦
Alphabetic—You can enter only letters.
