### 1031 F1 Will `toggle' the display so that usually non-displayed control characters are displayed in reverse video using the upper case letter that they are equivalent to. ### 1032 F2 Will `enter' the line that the cursor is positioned at. This is equivalent to the ENTER key on the HP-2621 and is the same as if you retyped the line. ### 1033 F3 Send a BREAK ### 1034 F4 Provides a sorted listing of the specified directory. ### 1038 F8 Freezes the display above the cursor. Handy to save some data on the upper portion so you can see it as you do other commands. ### 1039 F9 turns on the row/column display at the bottom of the screen so that you know where the cursor is currently positioned. ### 1040 F10 Toggles XON/XOFF. A convenient way of stopping/restarting the output to the CRT when connected to a system that honors the XON/XOFF protocol for flow control. ### 1061 Alt-F1 or Alt-255 Will terminate SIMTERM, but leave the DTR line high so that you can restart SIMTERM and pickup where you left off. ### 1062 Alt-F2 Terminate SIMTERM, and drop DTR so that the modem will hang up. ### 1063 Alt-F3 Toggles the DTR (data terminal ready) lead on the communications line. This is used to drop the carrier at the modem so that you can redial. ### 1064 Alt-F4 Toggles the graphics-mode. This will display characters with their parity bits so that the `graphics' characters of the PC (>127) are should. This is used on some of the BBSs. ### 1065 Alt-F5 Clears line 25 if it becomes cluttered. ### 1066 Alt-F6 Display various mode settings on line 25. ### 1067 Alt-F7 Resets the communications software. In some instances an interrupt might be missed and leave the system in a state where it is expecting data that will not be sent. If you suspect this, try an Alt-F7 before rebooting the software to see if it breaks you out of the situation. ### 1003 Alt-C Puts SIMTERM in a `capture' mode so that all input received over the communication line is logged to a disk file. Handy for picking up ASCII text from a system that does not support XMODEM. It will prompt you for a file name. ### 1004 Alt-D Will `dump' a ASCII file on the PC to the comm line. This is a way of `uploading' to a system that does not support XMODEM. ### 1005 Alt-E Toggles the `vi' mode. Handy when you exit SIMTERM and then come back into it with UNIX still in `vi'. The mode should be TRUE to have the cursor keys work for `vi'. ### 1006 Alt-F Enter the `local' line editting mode. This allows you to make corrections to a line and then reenter it. Use the cursor control keys to move to the line, `Ins' and `Del' to fixup the line and then hit return to reenter the line and leave the line edit mode. ### 1022 Alt-V Will display a menu that is used with the `auto-dial' capability of the Ventel. Once in this menu, select the desired feature. ### 1064 Alt-F4 Toggle parity mask. SIMTERM usually strips off the high bit before displaying a character on the screen. If you dial a board that uses character graphics, toggle this switch.
