First we will describe the minor differences between using the terminal directly to an
ADCC / ATP port on an HP 3000, or to a port on a PAD (HP 2334A).
1. Terminal configuration when used to a direct line (ADCC / ATP):
Figure L-3. Direct Connection to an ATP- or ADCC-Port
DATACOMM :
BaudRate : line speed (9600, 4800, 2400, 1200, ..)
Parity/Bits: Par/# of bits (None/8, 0’S/7, ODD/7, EVEN/7)
Enq/Ack : YES use enq/ack handshake
Asterisk : OFF no indicator is shown
Chk Parity : NO we don’t check for parity errors
SR(CH) : LO we don’t select any Baudrate
CS(CB)Xmit : NO we don’t use modem signals
RecvPace : NONE no XON and XOFF handshake is done
XmitPace : NONE on receive or transmit
NOTE Do not turn RecvPace or XmitPace to on at a 2392A terminal if it is connected
directly to an HP 3000. An XOFF (ctl S) could hang the terminal. (Only
POWER-OFF the terminal will reset this situation).
TERMINAL :
Datacomm/ExtDev : PORT1/PORT2
Keyboard : USASCII (or other keyboards)
LocalEcho : OFF the HP 3000 will echo
CapsLock : OFF we allow upper and lowercase
Start Col : 01 start column
Bell : OFF no right margin cell
XmitFnctn : NO move- and editor-keys are not transmitted to the computer
SPOW : NO spaces will overwrite existing characters
InhEolWrp : NO no wraparound at the end of line
Line/Page : LINE transmit one line at a time
InhHndShk : NO enable XON / XOFF handshake
Inh DC2 : NO ignored
Esc Xfer : NO transmit esc-sequences to the printer
TermMode : HP use HP special sequences
