USR Sportster Init String?

Post by chris losing » Tue, 09 May 2000 04:00:00



it's an external USR Sportser 56K faxmodem. my download speeds are
fine: (4k/). but my upload speeds are stuck at something like 1.1 k/s.

does anyone have a good init string (and jumper settings!) ?

and, where exactly are they issued?

this is my current ppp-on-dialer script


/usr/sbin/chat -v               \
        TIMEOUT         6       \
        ABORT           '\nBUSY\r'      \
        ABORT           '\nERROR\r'     \
        ABORT           '\nNO DIALTONE\r'       \
        ABORT           '\nNO ANSWER\r' \
        ABORT           '\nRINGING\n\n\n\nRINGING\r'    \
        ''              \rATZ           \
        'OK-+++\c-OK'   ATH0    \
        TIMEOUT         30      \
        OK              ATDT$TELEPHONE  \
        CONNECT         ''      \
        ogin:--ogin:    $ACCOUNT        \
        assword:        $PASSWORD

 And this is a bad init string. ATZ dumps in whatever some random
program or person once long in the past put into storage. Use AT&F1 for
Sportsters. Then you can look through the commands to see if thee are
some others which might be useful.

Try this:
AT&F1&B1&D2&H1&I0&K1&M4S7=60

        if i try this (or, "AT&F1") the CS LED comes on and stays on, the
TR light flashes on when ppp tries to dial, but it never dials.

        i tried setting my jumpers to load the factory defaults, but i get
the same results. if i set the jumper to load the 'last saved'
settings, it works as it did before - fast download, slow upload.

        i'm stumped.

        the USR website has some info, but none of it seems to work.

        sigh

Here I was, minding my own business, and wouldn't you know it?

        56K is one-way.  Downloading, you get 56K, but with uploading you only
get 36K.  Not enough bandwidth on the phone lines for bidirectional 56K.  
Maybe if you set yourself up as the "answering" modem rather than the
"originating" modem?  Try dialing out with ATDR to (R)everse the line
frequencies, see if that works...

  That's not the case, the 56k requires a digital connection at the
sending end, and your modem is analog (analogue in Cananda). If you had
a digital connection, which an ISP certainly does, you can eliminat one
level of D/A and just do D/A at the receiving end.

  As above, doesn't work that way, it's not a question of passing the
data (bandwidth) and one of getting it into the system.

1. Init String & 56K USR Sportster

I'm using a US Robotics Sportster 5686 modem to dial into my RH 7.0 Linux
box. I can connect at speeds from 26400 to 31200. Has anyone had luck with
faster connect speeds?

I'm thinking the init string may be the problem. This is the mgetty
configuration that sets up the modem.

# For US Robotics Sportster 5686 with speaker off
port ttyS1
speed 57600
switchbd 57600
init-chat "" ATZ OK AT&F1M0E1Q0S0=0 OK
answer-chat "" ATA CONNECT \c \r

Sugegestions?

Thanks,
Ken
