- CCSP.EXE: the CSP3 protocoll.
- =============================
-
- Status:
- Version 0.80beta.
-
- Known bugs:
- None so far...
-
- Hardware required:
- A SpeedModem.
- At least a '286/12, slower machienes might work,
- but with a performance penalty.
- The program needs ~150 Kbyte for itself.
-
- Description:
- CCSP.exe is an external protocoll to be used with
- BBSs and communication packages like PROCOM(+),
- Boyan, Telix, Qmodem...
- The installation depends on the package you are using.
-
- CCSP uses data compression to get your file over the
- the line faster. It does not rely on the error correction
- feature of the SpeedModem. It can (and should) be used
- with the *H1 setting for comm programs, BBSs use *h2.
-
-
- CSP3 is able to achieve up to a 4 to 1 data compression
- ratio, but only on certain ASCII files and some data files.
- If something is VERRY compressable using a program like
- PKARC or PKZIP then CSP3 will archieve excelent results.
- Already compressed files will not be compressed any more
- and CSP3 will not gain any speedup in these cases.
-
- Generally spoken: In cases where V.42bis will not
- compress the data any more, don's expect CSP3 to do so.
- In cases where MNP5 is used to some advantage expect a
- much higher compression rate from CSP3.
-
- A word of caution: CSP3 uses a lot of 'coputer muscle'
- to compress the data. If you have not at least a '286/12
- the compression might actually take longer than the
- transfer of data. You will not get the full performance.
- Receiving data on a slow machiene (downloading) should
- work fine, since the decompression is much less demanding.
-
- Usage:
- Upload:
- CCSP -b<baudrate> -p<port number> -t <filename>
-
- Download:
- CCSP -b<baudrate> -p<port number> -r <filename>
-
- Baudrates: 9600 / 19200
-
- Port Numbers: 1-4
- Filename: The name of the file to send/receive.
- On downloading the <filename> is
- optional. If no name is given, the
- file will get the name the sender
- supplied. In case of a name conflict
- the already existing file will not be
- overwritten, but the newly received file
- gets a filename with the last character
- changed to a numeric value.
-
- Examples:
- ccsp -b19200 -p2 -t c:\ul\test.txt
- This line will upload the file
- 'test.txt' on the c: drive in the
- directory \ul using com port 2 and set
- the baudrate to 19200.
-
- ccsp -b19200 -p4 -r
- This line will receive a file using
- com port 4 at 19200 baud. The name of
- the file will be the same as on the
- senders side.
-
-
- Setup for various communication packages:
- Help!!
- If you have set up CSP3 for ANY software, please
- share your wisdom. Drop me a message at the
- HQ BBS.
-
-
- Good Luck! and thanks for your help in beta testing CCSP.
