Have recently replaced a Winmodem with a full hardware type modem (ISA slot) that has seen my connections improve greatly. HTH Murray P	Guest (0)
53363	2002-06-09 11:09:00	Thanks for your tips Rodger, I'll take a look around that site this week. I don't get 56000bps now but I used to with zFree. With zFree I zipped around the web a lot quicker than I do now and the ISP I'm on now claims that their customers usually get 56000bps so I think my modem is a bit out of date. So is the computer, being a Pentium II 266mhz with 160mb RAM but it suits me at the moment. I was under the impression that the computer speed did not affect connection speed all that much, that it affected just the browser itself, but maybe I'm wrong there. I'd like to get a new hardware modem *if* it would make a difference but don't want to waste my money if it won't.	Guest (0)

Was 32600bps before that so now I know what the difference means. What brand and model modem do you have now? Also, PC specs? Sorry for being nosey but it all helps!	Guest (0)
53365	2002-06-10 02:00:00	Susan The paragraph below is a cutdown version of a posting I copied from this forum recently - it was from someone like Graeme P or Mike L. It includes some helpful info, especially about 'in reality' download speeds. A 56k modem has a theoretical maximum download speed of 56Kbits per second. This is 56000 bits per second = 7000 bytes per second = 6.8KB/s = 0.0067MB/s (there are 8 bits in a byte and 1024 bytes [2^10] in a kilobyte). Achieving the theoretical maximum speed is very unlikey - 3.5KB - 5KB is more realistic than 6.8KB. At 6.8KB/s a 1MB file will take 149.8sec (approx 2min 30sec) to download - a more realistic time is 3min 45sec. With a 266MHz computer you should have some ISA slots so you could use an internal hardware modem as I posted on a relevant thread a few weeks ago. I think you were a party to that thread but if not and you want to look it up post back and I will find the thread.	Guest (0)
53366	2002-06-10 05:04:00	There are 8 bits in an *octet*. I have used 'bytes' of 6 bits, 8 bits, and 9 bits. I have used 5 bit characters, and 'syllables' of 12 bits ... (More for the trivia collection). 8 bit octets in an asynchronous communications system are sent as 10 bits. There is one start bit and one stop bit for getting the two ends synchronised. (That's the simple bit -- there's also 2 stop bits for 110 baud, and 1.5 stop bits for the 5 bit Murray code 50 baud links). 'Speed' figures reported as 19200, 38400, 57600, 115200, etc, are the standard serial port *baud rates* at which the computer talks to the modem. The modem has a buffer so it can get and give several octets at a time when it talks to the computer. The external bit rate depends on what the two modems negotiate as the fastest they can run on the connection they have, with a maximum of '56k bps' download, and '33.6 bps' up. Funny speeds much higher which people boast about getting come from transferring files which can be compressed. This is done by software inside the modem (or the CPU with Winmodems). Two modems made to conform to the international V90 standard can't go faster. The 'bps' in modem speeds is not the same as 'baud' : the baud rate of the telephone line is about 2400. The difference comes from the magic.	Guest (0)
