R. Teague - 16 Nov 87 It has become increasingly obvious that there are some problems with using a Telebit Trailblazer with the WWIV Mac BBS. It is most acute when both the BBS and a caller are communicating at 19200 baud. From feedback from beta testers, and direct experimentation by a number of us, the following conclusions, and suggestions have been made : 1) Most terminal programs, and the BBS have been tested at speeds up to 57600 baud (in various combinations) over a direct connection, and they have all worked reliably with no problems noticed. 2) The speed of the sending and receiving machines make a difference to the reliability of file transfers - e.g. when communicating at 19200 baud, one or both machines should be as fast as possible (e.g. Mac II, or fast SCSI drive, with no additional software in the System file). In an experiment with a floppy based Mac 512e communicating with a hard disk based Mac II at 19200, the slower machine (Mac 512e) would have problems downloading from the faster machine, and when the roles were reversed, would have problems accepting uploads from the faster machine (to the extent that the file transfers would fail) - note this was only really a problem with XMODEM 1K blocks. 3) Whether it is due to a bug in the Telebit modem, or a bug in the Serial Port driver, or just inability for the hardware and/or software to keep up at 19200, it is not possible to upload using XMODEM 1K blocks using CRC - in what would be the normal mode of operation, the receiver sends the sequence 'CK' (or sometimes just 'C') to the sender as a prompt that XMODEM 1K is being used - if the sender can respond with 1K blocks, it will do so. However if it is not able to send 1K blocks, it will attempt to send a 128 byte block first, and then probably 1K blocks (this is how YMODEM generally works). The 'CK' sequence is not sent for XMODEM or XMODEM/CRC. What appears to happen when a file transfer is attempted at 19200 with XMODEM 1K blocks, is the sender will get the 'CK' and then try to send a XMODEM 1K block, which consists of 3 bytes overhead, followed by 1024 bytes of data, and finally 2 bytes of overhead (CRC). But the problem is, the receiving end only receives approximately 3 bytes overhead followed by 1021 bytes of data and CRC. Consequently, it fails with a CRC error on the first block, and then do retries without success. This only fails in the above configuration. If the first block is only 128 bytes, there is no problem. It does not seem to matter what protocol the modem is using. There are two possible solutions (sort of) - one, the BBS software has been modified to detect the attempt to upload a first block of 1K at 19200 using CRC, and when it fails, aborts the upload immediately. The other solution works best with MicroPhone 1.1 - simply disable CRC and enable YMODEM - the BBS software has now been modified to cancel the attempt by Microphone to send an end of YMODEM Batch marker, and so there is no longer any necessity for the user to manually terminate the upload. 4) It can be frustrating when file transfers fail, but it is made even more frustrating because of the high speed and large buffers in the modem - more data gets sent even after the file transfer is aborted (or what usually happens is that one end won't know the other end has failed until several block later because of the buffer, and so retries causing all sorts of problems). The BBS is not perfect either, and sometimes it can be difficult to abort a file transfer manually. Many users expect their terminal software to automatically send the correct abort codes to the BBS when they wish to manually abort a file transfer - this is not always the case. The file transfer prompt is "^X to abort" - meaning if the file transfer doesn't seem to have been aborted yet, try sending some Control-X's from the keyboard. Generally, the BBS will eventually time out of any difficulty. Another special problem seems to be related to the use of the Telebit and Microphone 1.1 - sometimes when a file transfer is aborted, the user loses control of his keyboard. Sometimes this can be cured simply by pressing Control-Q (XON), and allowing the frozen display to re-appear (i.e it is not a good idea to use Control-S (XOFF) to pause the BBS output - use the P key instead). Other times, the user may have to go offline on his modem, and enter some kind of re-initialization command, and then go back online. And finally in some cases, things simply lock up, and there is no recourse but to drop carrier, exit Microphone and return. The reason for these problems haven't been discovered yet. ΓÇóThis is a Telebit help file in setting up the bbs with the telebit trailblazer on a PC XT, AT or 386 machine: 1. Set the init.exe to USE FLOW CONTROL and NOT STAY AT HIGHEST SPEED.. 2. If ya dont want 300 baud users take out the response for the 300 baud callers or change it to 3 which is NO CARRIER. 3. Unless you have a USR HST take out the response for 9600. 4. Now, here is a register dump of my telebit yours should look the same: THESE ARE THE REGISTERS AS SET FOR THE TELEBIT TRAILBLAZER WITH THE 3.01 ROMS, YOUR SHOULD LOOK LIKE THESE..

As for external file transfers i am using DSZ from Chuck Forsburg's BBS, to get the most out of it i suggest you register it for 25 bucks and you will get a serial number you can put in and have the added features you need..this is for Mac users to be able to upload and download using Microphone 1.1, 2.0 and Red Ryder 10.x, Smartcom 3.0 bxx and VTP 4.0 5. DSZ.ARC can be obtained by calling 503-621-3746 (DATA 12/24/19.2) 6.. set your externals as follows.. XMODEM 1K CRC recieve line dsz handshake cts pB2048 z pr1 rx -kc %3 send line dsz handshake cts sx -kc %3 XMODEM 1K recieve line dsz handshake cts pB2048 z pr1 rx-k %3 send line dsz handshake cts sx -k %3 YMODEM-g recieve line dsz handshake cts pB2048 rb -g %3 send line dsz handshake cts sb %3 ZMODEM recieve line dsz handshake cts pB2048 rz -r %3 send line dsz handshake cts sz -r %3 Note: ALL OF THE ABOVE SETTINGS ARE FOR COM PORT 1 COM PORT 2 CAN BE USED BY ADDING AFTER dsz port 2 7. You can also get a LOG of all the file transfers by puting in your bbs.bat file as follows: SET DSZLOG=D:/BBS/GFILES/TRANSFER/DSZLOG Now add the gfile directory call TRANSFER and your log will be saved there,upload the log to the gfiles section and now your users can view the transfer "characters per second". 8. Once this is done your ready, any problems leave me some mail on The Orginal BBS 213-208-6689 or on GEnie to Cove Keeper and i should be able to help ya.. Cove Keeper
