- Evidently there is a great deal of problems/concerns regarding the
- reliability of the PCP Direct connection. As a frequent user of this board
- and others BBS's in the country that are PC Pursuitable, I have decided to
- provide some hints for all regarding some problems noted and actual d/l
- specifications. I hope that it helps.. Any comments, or prroblems I remain
- more than happy to answer.
- Parameters:
- To PCPursuit (local) I connect at 7E1. Then the direct connection is
- made to EXEC-PC (per instructions in EXECTELE.TXT). Once connected, I am
- in the habit of switching to 8N1. All of the above is done with a 1200
- baud (US robotics Courier) with Procomm v2.4.2.
-
- Some problems noted:
- At the outset, I must admit that not all of my downloads have been
- flawless with using PCPursuit. I have found that the direct connection is
- more reliable than the old approach (through Milwaukee node ...).
- The download protocol which I used with the "old" approach was the
- special (slowdown) Ymodem available here. However, with the direct
- connection, I always use Ymodem.
- It should be noted that the mere presence of a BAD CRC does not indicate
- that the ARC is not good. I have found the Ymodem protocol to be
- particularly well behaved in the "recovery of" errors (i.e. popping sounds,
- electrical interference). After the file has been downloaded, use PKARC/V
- to verbose list the ARC.
- It is also important that you correctly identify the source of the "BAD
- " archive download.
- 1. Is it the file itself (i.e., the file on EXEC-PC is corrupted: rare
- but it does happen).
- 2. Is the problem "with the direct connect"
- 3. Is the problem with "normal PCPing" (i.e., old way)
- 4. Is the problem due to the download protocol
- 5. Is the probelm due to the communication software
- 6. Is the problem due to the hardware (i.e., loose RS232, CB
- interference)
-
- One particular anamoly that I have found concerns certain ARCs that have
- several files in them that have been squashed. While I was unable to
- pinpoint the necessary conditions, PCP seems to dislike squashed files that
- are approximately 512 bytes large or less. You are made aware off this
- condition when your computer begins to beep for approximately 3 minutes and
- then drops you to the node level ("@"). In order to get around this
- problem, I have patched PKARC tochange the default archive standard to be
- crunching. This file is available on this board (search for PKARC).
- After you PKARC/F the archive, the error no longer occurs on upload.
-
- If you are still having problems, please feel free to leave a message for
- either myself (or address one to Bob Mahoney and he will direct you to
- myself). I will be happy to elaborate further.
