Only disadvantage is: IBM PS/2 models For the record: Brooklyn Bridge runs over either the parallel or serial cable. If you use parallel, you get 500,000+ bps. If you use the serial port, you get up 115,600 bps. The serial cable is a regular "null-modem/turn- around" cable. The parallel cable (supplied with BB) is a special cable although it wouldn't be hard to make. (BB supplies both cables.) Laplink II runs only on the serial port with speeds up to 115,600. I think LapLink III runs on both serial and parallel. Recently, PC Magazine ran a comparison but I don't remember the details or how far back in time that was. BB also comes with some nice features. You can run there filer program or your own. You basically set it up so that drives ABC on one machine become DEF on another and various configurations. ----------------------------------------------------------------- Michael Bower - N4NMR Honeywell Federal Systems Inc. e-mail: uunet!hfsi!bower 7900 Westpark Drive. phone:(h) 703-435-5081 (o) 703-827-3559 McLean, VA 22102 -----------------------------------------------------------------

However, in the above article it was stated that it used the serial port instead of the parallel port, not true, Brooklyn Bridge (the version I have anyway) uses either the serial or the parallel port, your choice. And, naturally, since it has more lines, the parallel port method runs much faster than the serial port method. I have had no trouble using it at full speed through the parallel port on the IBM PS/2 model 30 and 30/286's. Very nice program, good recommendation. -- John Joubert | /\ | /\ | _ Internet: pabres13@pc.usl.edu | \|<>|>|> \|<>|>|><`|`| GENIE: J.JOUBERT |--/|-------/|------------ | \/ \/

The above certainly "sounds" obvious, but can it be "done" obviously? I am not talking about the physical size of a hard drive (you probably don't want to fit the AT drive into a PS/2, close the cover, screw and secure everything to do the copying and afterwards open up the machine again to get the HD out 'cause that's stupid), what I mean is can you grab an AT hard disk (any hard disk) and simply stick it into the PS/2 controller? As far as I remember, for a PS/2 Model 50z, the hard drive plugs right into the ESDI controller card. There is no cable or anything, not to mention a spare one for a second drive. I am not sure if you can have more than one drive in some of the PS/2 models either. If it can really be done, can you post/e-mail more details as to how exactly one would do the thing you suggested?

Now, that's the general answer, now here's some specifics : Use Procomm on both systems (Comms program). On the 'AT' set Procomm into 'HOST MODE', 'DIRECT' connect. On the 'PS/2' (Ugh, fire him :-)), use Procomm to access the 'AT' as a direct connection, NOT a modem link. Doing it this way you can then use any one of the various file transfer protocols available within Procomm. It is possible to use 'wildcard' characters when using the Kermit protocol. So, set you 'AT' directory, set you 'PS/2' directory, setup for Kermit tranfser using : "*.*" as the file to copy, then go home. :-) >S/he seems to have missed the obvious.. >Remove AT hard disk drive. >Fit it in PS/2 as drive 2. >copy d:\foo.bar c: >for LARGE chunks, there's no faster way.. I agree that this is THE fastest way to do it, however, it is NOT possible. The PS/2 is NOT hardware compatible, so you can NOT plug your 'AT' hard disk controller into it. Without it, you can not access the data that resides on the drive. The PS/2 controller accesses date on a hard disk in a different way to the 'AT's' controller. So, whether or not you can even physically connect the 'AT' HDD to the PS/2 HDD controller, it won't matter. NOTE: Kermit for the PC, or for that matter any decent comms program, could be used instead of Procomm. There are a number of commercial products specially designed for this sort of job. Many of them are probably easier to use and fast in transfering files than what I have proposed, however, they cost money.

Further to my previous followup posting : There is a product called : "Hot Wire" - File transfer & Disk management. Contact the developers : Datastorm Technologies, Inc. 3212 Lemone Blvd., (P.O. Box 1471) Columbia, MO 65205 Phone : 1-314-443-3282 Fax : 1-314-875-0595 This product is written specifically to solve the problem of file transfer between two systems. It comes with : - Software on 3.5" & 5.25" diskettes, - Special 7' "four-headed" universal null modem cable with twin 9 and 25 pin connectors, - Simple installation program, and - 288 page manual with tutorial. It's obviously not free, but it sounds good. Give them a call. If you should buy it, would you please post an evaluation of it? I'm sure that there are others who would be interrested. :-) -- Brad Willcott, ACSnet: bxw@ccadfa.cc.adfa.oz Computing Services, Internet: bxw@ccadfa.cc.adfa.oz.au Australian Defence Force Academy, UUCP:!uunet!munnari.oz.au!ccadfa.oz!bxw Northcott Dr. Campbell ACT Australia 2600 +61 6 268 8584 +61 6 268 8150 (Fax)
