50 Setup
HOST: F7
Comm Mode: [Full Duplex, Half Duplex, Full Block, Half Block]
Select the communications mode.
Half-duplex is not available when KeyMode is ScanCode.
Receive <CR>: [<CR>, <CR><LF>]
Select the way in which carriage returns received will be
interpreted.
Receive <DEL>: [Ignore, Destruct <BS>]
Choose to ignore the DEL control code (7Fh) when received or to
treat it as a Destructive Backspace code.
Send ACK: [Off, On ]
Decide whether the terminal should respond to inquiry (05h) or
when certain terminal functions are performed (configuring the EIA
(Aux) ports, splitting screen, etc.) with the ACK (06h) character.
Null Suppress: [On, Off]
In the default mode, the host ignores all received nulls (00 hex).
When off is selected, the terminal will accept all received nulls,
and act upon them according to the selected emulation.
Send Line Term: [<US>, <CR><LF>]
Select which line terminator is sent. <US> is 1Fh and <CR><LF>
is 0Dh 0Ah.
Local: [Off, On]
Select whether keyed data is interpreted locally by the terminal
and not sent to the host. Data sent by the host is lost, if Local is
on. The ability to print data is not affected by this mode.
Send Block Term: [<ETX>, <CR>]
Select which character will indicate the end of a block. The
choices above are for ASCII emulations. ANSI emulations have
the following choices: [None, FF].
Send End: [Cursor, Region]
