- NAME:
- ckcd
-
- SYNOPSIS:
- ckcd [1 | 2]
-
- DESCRIPTION:
- ckcd is a small utility for checking the status of the
- carrier detect (CD) line of an IBM PC's serial port. ckcd
- accepts an optional COM port number on the command line
- (COM1: and COM2: are supported). If no port is specified,
- COM1: is the default. ckcd prints a message to the screen
- and then exits with a DOS ERRORLEVEL corresponding to the
- state of the CD line. An ERRORLEVEL of 1 indicates the CD
- line is high for the specified port; an ERRORLEVEL of 0
- indicates the CD line is low.
-
- A sample batch file illustrating the use of ckcd is
- included.
-
- MANIFEST:
- CKCD.COM - The program itself

- COPYRIGHT INFORMATION:
- ckcd is made available under the sourceware concept. This
- simply means that although the program is copyrighted, the
- complete source code is distributed along with the
- executable file. No fees are required for its use; all I ask
- is that if you find ckcd useful, please send me email at one
- of the addresses below with your comments, suggestions, or
- just to say "hello".
-
- Feel free to distribute ckcd to your friends, local
- bulletin boards, users group library, even on line services
- which charge their users exorbitant fees. A reasonable disk
- duplication fee (<= $1.00) may be charged. If you improve,
- fix, or otherwise modify ckcd, please send me a copy - I'd
- like to see what you've done.
