Note 0029  Entering escape sequences in UNIX using VI.

SOLUTION: The procedure to enter PCL, HP-GL/2, and PJL commands in a UNIX environment is the same as for the DOS environment in every aspect except for the escape character itself. The procedure for entering the escape character is detailed below.

  1. At any UNIX prompt, type:
    vi
    (this brings up the vi editor)
  2. While in vi, type:
    I
    (this enters into insert mode)
  3. Type:
    <Ctrl>V
     (press and hold the <Control> key while tapping the V key once, then release <Ctrl>) which changes keyboard to verbose mode; then press the <Esc> key.
    Or, type:
    <Ctrl>V <Ctrl>[
    The escape character will appear as follows: ^[
  4. Enter the remaining part of the escape sequence. For example &f123y4X to overlay form number 123 on the page.

NOTE: The escape character always shows up as ^[. If it does not, an incorrect character has been entered.
