Code Sets D-5

Table D-2. AMT and Diablo 630 Control Codes
Function ASCII Hexadecimal Decimal Description
Ignore................................. NUL 00 0 The printer ignores this code unless it is used within an
escape sequence.
Continue printing?............ ETX 03 3 With the ETX / ACK serial handshake in use, this code
causes the printer to return an ACK control code when it
can receive more data. When ETX/ACK is not in use, the
code prints the assigned character.
Bell...................................... BEL 07 7 This code sounds the audible alarm for a brief period.
Backspace .......................... BS 08 8 This code moves the current print position one character
space to the left. If the current print position is the left-
most, the printer ignores this code.
Horizontal tab.................... HT 09 9 This code moves the current print position right to the next
horizontal tab stop on the current line. If no tab stop is set
to the right of the current print position, the audible alarm
sounds and the printer ingnores this code. If the factory
defaults are in effect, tab stops are set every eight print
positions across the page.
Line feed............................. LF 0A 10 This code advances the paper one line space. If the current
line position is the last printable line on the page, the printer
performs a form feed instead of a line feed.
Vertical tab........................ VT 0B 11 This code advances the paper to the next vertical tab stop.
If no vertical tab stop is set below the current line posi-
tion, the audible alarm sounds and the printer ignores
this code.
Form feed........................... FF 0C 12 This code performs one of the following actions:
9If a single sheet is loaded, the printer ejects the sheet.
9If pin-feed paper is loaded, the printer advances the
paper to the next top-of-form or top margin if one is set.
9If an automatic sheetfeeder is installed, the printer loads
a new sheet from the active bin. The sheet feeds to the
top-of-form or top margin if one is set.
Carriage return................ CR 0D 13 This code moves the current print position to the left mar-
gin. If automatic line feeding is active, the printer performs
a line feed in addition to the carriage return.
Enable characters with..... SO 0E 14 This code causes one of the following actions:
codes outside normal range
9If an ECS font is not active, this code permits the print-
ing of characters with codes below 20 hex. After re-
ceiving an SO code, the printer does not perform the
usual control functions of subsequent control codes it
receives, but instead prints the assigned characters. An
ESC SI sequence ends this function.
