I have found the 2400SA to be a dependable modem. But, you're right, the manual leaves much to be desired. This may, however, have as much to do with the complexity of the subject of communications as with the quality of the explanation of the operation of the modem. -- Bob Breedlove SYSOP: BOBsBBS (916/929-7511) 3/12/24 - 8-N-1 - 24 hours - MS-DOS Operating System pacbell!sactoh0!bfbreedl

I've owned one now for close to a year. The last 2400 BPS modem I
tried was a Everex, and that was junk compared to the 2400SA.
I've notice a bug in the firmware. If you are dialing out, and have
call progress enable (that's where the modem says BUSY if the called
number is busy), and the modem you call up answers the phone BEFORE you
get a "RING" on the line, the 2400SA just hangs there. It's not locked
up or anything, it just doesn't know that a modem has answered the call.
Since the VAX system here at UNO loves to answer the phone that way, I've
had to permantly disable that feature.
As for the manual, it's lousy. But I've seen worse. At least it has
an index, and documents all or most of the commands.
The NVRAM I just love. DIP switches? Not one in sight. As for keeping
phone numbers in NVRAM, I've finally used it when the Amiga the 2400SA went
in to work, and the 2400 stayed home with the VT100. Makes it easy to
dial the same number that the ol' terminal program did..

I agree that this modem is a terrific buy, but I don't think that you can say that it's "100% Hayes compatible". The synchronous mode of a Hayes 2400 is not supported. Many of the "ATS=xx" commands are not rejected by the the Practical Peripherals 2400SA, but they also are effectively "no-ops". Clearly you don't care about those, and I don't either. I'd say it's compatible with a Hayes to the extent that it does everything I need done. Buy it. Not over $180 these days in the US, I don't know about Israel. >P.S. Are all you 2400SA owners satisfied with it's manual? No. Its manual is not the worst thing I've ever seen, and it doesn't say anything wrong, but I've read it more times than I should have to, and more times than many of the classicly terse Unix manual pages. Once you know what it's all about, then the manual is perfectly clear. And the index is barflegarbij. -- Jean-Pierre Radley Honi soit jpr@dasys1.UUCP New York, New York qui mal ...!hombre!jpradley!jpr CIS: 76120,1341 y pense ...!hombre!trigere!jpr

You mean, "its" manual...no...I've seen much better...consider Prometheus, which even had bit-mapped I/O registers to aid programmers. And much better definition of commands and such. However, the 2400SA -is- a very good modem. I recommend it too...

Never heard that before... I said it. The manual is clear at least in this regard: certain of the S-registers descriptions carry the notation SSNIH. This is explained as "Software Supported Not Implemented in Hardware". These are S-register settings having to do with synchronous operation, which the PM2400SA does not support. You will not get an ERROR if you try to affect one of these registers with an AT command, you'll get an OK. But the modem really does nothing differently as a result of the command, so why shouldn't I call it a NO-OP? -- Jean-Pierre Radley Honi soit jpr@dasys1.UUCP New York, New York qui mal ...!hombre!jpradley!jpr CIS: 76120,1341 y pense ...!hombre!trigere!jpr
