Titolo: Stringa x limitare veloc. in modem con chipset Lucent

Mi servirebbe una stringa per limitare la velocità del mio modem che monta
un chipset Lucent! E' urgentissimo!
Grazie!

Prova con +ms=11,1 o, se il modem e' interno, con +ms=v34,1.
Ciao.

Ma perchè vuoi abbassare la velocità quando tutti la vogliono alzare il più
possibile? Mi incuriosisce ciao.

Prova con questo comando (per modem V90):  AT-V90=x
(Downstream Rate) dove x può assumere:
0     V.90 disabled
1     Auto Rate (default)
2     28000 kbit/s
3     29333 kbit/s
4     30666 kbit/s
5     32000 kbit/s
6     33333 kbit/s
7     34666 kbit/s
8     36000 kbit/s
9     37333 kbit/s
10     38666 kbit/s
11     40000 kbit/s
12     41333 kbit/s
13     42666 kbit/s
14     44000 kbit/s
15     45333 kbit/s
16     46666 kbit/s
17     48000 kbit/s
18     49333 kbit/s
19     50666 kbit/s
20     52000 kbit/s
21     53333 kbit/s
magari da usare insieme ai registri:
S37     Dial Line Rate (default 0)
This register sets the maximum line data rate. In K56flex and V.90 mode, S37
controls the upstream V.34 rate.
S37 = 0     auto rate
S37 = 1     reserved
S37 = 2     1200/75 bit/s (V.23)
S37 = 3     300 bit/s
S37 = 4     reserved
S37 = 5     1200 bit/s
S37 = 6     2400 bit/s
S37 = 7     4800 bit/s
S37 = 8     7200 bit/s
S37 = 9     9600 bit/s
S37 = 10     12000 bit/s
S37 = 11     14400 bit/s
S37 = 12     16800 bit/s
S37 = 13     19200 bit/s
S37 = 14     21600 bit/s
S37 = 15     24000 bit/s
S37 = 16     26400 bit/s
S37 = 17     28800 bit/s
S37 = 18     31200 bit/s
S37 = 19     33600 bit/s
e
S38     K56flex Downstream Rate
To force a particular K56flex downstream rate, use S-register S38. S38=0
disables K56flex, and may allow a
more reliable V.34 connection. S38=1 default allows the modem to select the
downstream rate automatically.
Other values of S38 force the downstream rate, with fallback to V.34 if
unsuccessful at the configured rate:
S38=0     Disable K56flex
S38=1     Automatic rate selection (default)
S38=2     32 kbit/s
S38=3     34 kbit/s
S38=4     36 kbit/s
S38=5     38 kbit/s
S38=6     40 kbit/s
S38=7     42 kbit/s
S38=8     44 kbit/s
S38=9     46 kbit/s
S38=10     48 kbit/s
S38=11     50 kbit/s
S38=12     52 kbit/s
S38=13     54 kbit/s
S38=14     56 kbit/s
The number of robbed-bit signaling (RBS) frames detected decreases the true
DCE rate per the following table:
RBS links     Rate hit (kbit/s)
    0                         0
    1                         2
    2                         4
    3                         4
    4                         6
    5                         8
    6                         8
For example, if S38=10 and there are 3 RBS links, the K56flex downstream
rate will be 48-4=44 kbit/s. The
exception to this is for 32 kbit/s and 34 kbit/s, which are the true rates
regardless of the number of RBS frames
detected.
One special value of S38, S38 = 251, is used for back-to-back (factory)
testing of V.34 rates, with DSP code
running in external memory. Set S38=251 on both originating and answering
modems. (This feature is not valid
with ramless solution.)
