HP 48gII Graphing, 50g Graphing manual Reserved Variables D5

Parameter (Command)	Description	Default Value
baud (BAUD)	The baud rate: 2400, 4800, 9600, 14400,	115200
	19200, 38400 or 115200.
parity (PARITY)	The parity used: 0=none, 1=odd, 2=even,	0
	3=mark, 4=space. The value can be positive
	or negative: a positive parity is used upon
	both transmit and receive; a negative parity
	is used only upon transmit.
receive pacing	Controls whether receive pacing is used: a	0 (no pacing)
	nonzero real value enables pacing, while
	zero disables it. Receive pacing sends an
	XOFF signal when the receive buffer is
	almost full, and sends an XON signal when
	it can take more data again. Pacing is not
	used for Kermit I/O, but is used for other
	serial I/O transfers.
transmit pacing	Controls whether transmit pacing is used: a	0 (no pacing)
	nonzero real value enables pacing, while
	zero disables it. Transmit pacing stops
	transmission upon receipt of XOFF, and
	resumes transmission upon receipt of XON.
	Pacing is not used for Kermit I/O, but is
	used for other serial I/O transfers.
checksum (CKSM)	Errordetection scheme requested when	3
	initiating SEND:
	1=1digit arithmetic checksum
	2=2digit arithmetic checksum
	3=3digit cyclic redundancy check.
translation code (TRANSIO)	Controls which characters are translated:	1
	0=none
	1=translate character 10 (line feed only)
	to / from characters 10 and 13 (line feed
	and carriage return)
	2=translate characters with numbers 128
	through 159 (809F hex)
	3=translate characters with numbers 128
	through 255.

Parameters without commands can be modified with a program by storing new values in the list contained in IOPAR (use the PUT command), or by editing IOPAR directly.
