- Jeff Prosise 1989 No. 5 (Utilities)
-
-
- Purpose: Replaces an RS-232 breakout box by
- displaying the status of the DTR, DSR, RTS, CTS, DCD, and RI
- pins; also indicates the data rate, parity, number of data
- bits, and number of stop bits of the serial port being
- monitored.
-
- Format: LITES [comport] [U]
-
- Remarks: LITES is a memory-resident utility and may
- be loaded either at the DOS prompt or as part of an
- AUTOEXEC.BAT file. If no communications port is specified,
- the default comport monitored is COM1. After loading,
- alternately pressing Alt-L (the default hotkey) pops up and
- cancels the onscreen display, which is located (by default)
- in the upper right corner of the screen. LITES can be
- deinstalled by entering it with the optional u (or U)
- parameter, which simplifies changing the comport to be
- monitored. (Do not precede the U with a slash.)
-
- The various default options of LITES can be changed
- with DEBUG.COM. The procedure is explained in the printed
- article, which also contains full tables of scan codes,
- shift masks, colors, and the like. The available patch
- points, bytes allocated, and default values are listed
- below.

- Available for downloading from PC MagNet (see the
- LITES by Modem sidebar), LITES.COM is already compiled and
- ready to run. LITES.BAS will automatically create LITES.COM
- when run once in BASIC. To create LITES.COM from the
- LITES.ASM source code requires use of a macro assembler (IBM
- or Microsoft, Version 2 or later) and the following
- commands:
-
- MASM LITES;
- LINK LITES;
- EXE2BIN LITES LITES.COM;
