8.2 Control Code Details

(1) Command for Line Feed After Printing (CR/LF)

By entering CR (0DH)/LF (0AH) codes, data in the print buffer is printed followed by a line feed. Without data in the print buffer, only a line feed is performed. This command is ignored just after buffer full in case of 920 emulation.

CR and LF are valid in the following conditions.

CBM-920 Emulation		SW1 Switch No.1
		OFF	ON
	Serial	LF only	CR and LF
	Parallel	LF only	CR and LF
iDP3110 Emulation		SW2 Switch No.2
		OFF	ON
	Serial	CR only	LF only
	Parallel	LF only	CR only

(2) Specify/Clear double-width character (SI, SO, US, RS, and DC4) command

SI/SO codes function in the same manner as US/RS as long as 8-bit data are assigned (serial communication data bit length), which, however, are divided, under 7-bit assignment, into SI (20H~7FH characters) print assignment and SO (A0H~FFH characters) print assignment functions.

1.Standard letter assignment (SO/RS) command:

With SI (0FH)/US (1FH) codes input, lateral enlargement is cancelled and the data following are printed in standard letters. This command can cancel only lateral enlargement, which dose not apply to ⋅4 enlargement.

2.Laterally enlarged letter assignment (SO/RS) command:

With SO (0EH)/RS (1EH) codes input in any columns, the data following are printed in prints enlarged double in width.

Although standard and enlarged letters can be mixed within one line, automatic (buffer-full) printing takes place when the number of columns reaches 24 (or 40) counted in standard letters. With 920 emulation, laterally enlarged letter assignment is cleared by printing after line feed, followed by SI, US, and DC1. With 3110 emulation, it is cleared by printing after line feed by LF and CR, followed by SI, US, and DC4.
