Tape Output; Printer; Bypass Function (Print Inhibit) - IBM 5100 Communications Manual

Tape Output
When the tape is used for output, messages transmitted and received are written
on tape, provided the tape was previously marked. The
~OUTSE
L command
specifies the lines to be written
on
tape, and the
~OPEN
command opens the file
and defines it as an output (OUT or ADD) file. For an OUT file, data is written
starting at the beginning of the file. For an ADD file, the data is written following
the last existing data on the file and always uses at least 512 character positions.
The output file created is a type 2 file if the file is an OUT file and remains as is if
the file is an ADD file.
Note: No checking is done on OUT files, and any file can be overwritten.
Tab, line feed, and backspace function characters are not written on tape. Tabs
are simulated by inserting the correct number of blanks in the data, and line feed
characters are simulated by writing a new-line character and the correct number of
blanks to indicate the start of the next line. Valid overstrike characters are written
as one character.
PRINTER
The
~OUTSEL
command controls which lines will be printed if the printer is on
during communications. When using option T, the lines are printed after the
complete message is received or transmitted. When using option P, the lines are
printed as each line is received. If you are using preprinted forms, the character
spacing on the printer is 10 characters per inch and the line spacing is six lines per
inch.
With option T, the message size is restricted by the size of the extended display.
The maximum message size is at least:
5100 Model
A1, B1, C1
A2,B2,C2
A3,B3,C3
A4,B4,C4
Size
1K (K=1024 characters)
17K
33K
49K
The maximum printer width is 132 characters. If the lines are longer than 132
characters, an OUT (0 backspace U backspace T) character is printed in position
132 and any characters beyond position 131 of the line are not printed.
BYPASS FUNCTION (PRINT INHIBIT)
The bypass function is activated by the remote system to inhibit output from the
5100 for security purposes. To ensure data security, you should not use the edit
operation or the
~TAPEIN
command when the bypass function is active. Use the
home key to reset the bypass function to normal. When bypass is active, characters
typed on the keyboard will be sent (the cursor advances with each keystroke), but
not printed or written to output devices.
