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.
