Modem Strings [was: Tech Time 8: Modem Contact]

I am the walrus
in Zocalo v2.0
So I have an extrernal serial 56k modem that only connects at 28.8 with the usual ATZ init string. Now Biggles says that the modem was connecting slow because it isn't configured right. So with the string AT&F&H2&I2&B1&K1&M4 I now have a 33.3 ish connection. Alas I am stumped. So I am asking all of my wonderful friends here at firstones for their help :)

'bout all I can think of at the moment
;)
And as for the broadband suggestion...
Croxis may be fortunate enough to live in an area that can reiceve broadband, but there are more then a few places outside of portland that cannot get any form of broadband at all, because they are not served by cable, and the phone lines can not handle DSL.

Speaking of modem problems, my winmodem drops the connection on uploads (FTP) after uploading between 500k and 1MB. Any ideas?
Note: the other computer in the house has no problem with uploads on its modem.
[B]Speed depends also greatly on phone line, if it "rusted barbwire"... well, I guess you got the point. [/B][/QUOTE]
As mentioned, the winmodem connects fine at 56k, so the line itself is not likely to be the problem.
Do you have modem's manual which would explain AT commands and registries used by settings?
One of my modems had too short dial tone waiting time as default so it required adding one command to dial command. Then I read manual and found AT command which saved longer dial tone waiting time to registry as default setting.
[B]yes I thought it was line problems at first, but our house is almost brand new and like it was mentioned our win modem goes full speeds. Now if I could just get the win modem reconized in linux..... [/B][/QUOTE]
Have you tried [url=http://linmodems.org/]Linmodems[/url]?
...
I think it's either the AT settings or its your serial port connection...
;)
I haven't managed to download the manual yet so I know of no specific details.
There is no native winmodem support (i'm using freesco)
I don't have gunzip to use linmodem (working on trying to get that)
And the computer is 9-10 years old, I don't know if that would be too old tho.
[B]ok time ot attack this:

Is it a 486, Pentium ???
Are the serial port(s) built in or on a PC expansion card?
Not all Serial cards used 16550 UART chips, and if this is the case, you'll have to get a newer serial port of some kind.
9-10 years old is on the border line of when both types were being used (1994-95). And for the newer modems you had to get one with the 16550.
Your winmodem has it built in, so that's why it is not an issue with that one. ;)
[B]Jack, unless his computer is a dinosaur, I think it can handle 16550 UART. [/B][/QUOTE]
Well... I guess we'll find out... :p

However, it doesn't explain why its running slow on newer systems like mine.. Someone on nother forum suggested that its damage to the 'front end' of the modem and should be fixable with some electronic experiance ;)
Yes I am two timing you guys!
