Dial Up Modem Sounds After Connecting: V.FC
This is a companion to the first V.FC video: ruclips.net/video/cS7cR7XPc2E/видео.html
This time the audio continues after the connection is established, letting you hear what is going on once the speaker turns off.
What you hear is mostly just white noise. V.FC is a pretty typical case, as it sounds similar to most other modem standards after the connection is established.
However, some modem standards have much more interesting connection sounds afterward, such as Telebit PEP, and Courier HST. Check them out below!

This is a companion to the first Telebit PEP video: ruclips.net/video/uOZT8WRWFhU/видео.html This time the audio continues after the connection is established, letting you hear what is going on once the speaker turns off. The 'ping pong'ing back and forth between the two modems can be clearly heard here, and this happens when the connection is idle. The Telebit protocol uses a large number of c...

This is a companion video to the first Courier HST video: ruclips.net/video/itkYiepHEJY/видео.html This time the audio continues after the connection is established, letting you hear what is going on once the speaker turns off. Courier HST is an asymmetrical protocol, where one direction runs at a much higher speed than the other. In this case of this call, it's 16800/450. Since the rates are s...
Dial Up Modem Sounds: US Robotics Courier HST (viewer request)
Просмотров 239Месяц назад
@jrherita requested a recording of Courier HST, so here it is! USR introduced Courier HST (High Speed Transfer) in 1986. HST provided 9600 bps at a time when a fast common modem would be using V.22bis (2400bps). The standard was expanded twice: once in 1989, adding 14400bps and 16800bps, and again in 1992 to 21000bps and 24000bps. Presented here is an example of a connection at 16800bps, though...

Dial Up Modem Sounds: V.32ter
Просмотров 5184 месяца назад
Thanks to @FairPlay137 for suggesting an 'oddball connection standards' series! Here's V.32ter, though it doesn't really sound all that much different from plain old V.32. Still fun to see it connect at 21600 though, especially since most modems seemed to only do 19200 with this sort of 'overclocked' V.32. Upcoming modulations: X2, K56Flex, and Telebit Trailerblazer PEP If there's something els...

56K Modems Aren't Always 56K
Просмотров 3,5 тыс.2 года назад
This is a quick explanation of why two analog 56K modems won't negotiate a 56K connection to one another, and why it's necessary for at least one of the modems to be digital in order to get a 56K connection. This is my first attempt at using After Effects, and a test for the more in-depth videos in the pipeline. As always, thanks for watching.
Modem Sounds Explained, Part 1: Audio Frequency Shift Keying and Bell 103
Просмотров 10 тыс.2 года назад
I've gotten a number of question on my modem sounds videos about the meanings of the sounds. This video is the first in a series that will explain their meaning, and together they'll cover the evolution of modem negotiation. Up first, we talk about modems that don't really negotiate at all! This is Audio Frequency Shift Keying and Bell 103.

This is a follow-up to the earlier modem sounds video here: ruclips.net/video/xalTFH5ht-k/видео.html The sound of 56K for various modem models and standards. Prior to V.90 there were competing x2 and K56 Flex standards, which are included here. Even when V.90 was official though, different models of modems tended to sound different from one another when connecting. This is the result of part of...

This is a more elaborate version of the setup used in an earlier video: ruclips.net/video/p0d2ogyQ0ys/видео.html In that video I'm dialing into a server using a terminal and letting that server handle TCP/IP instead of the local machine.

Hall Kenneth Robinson Nancy Brown Mark
0:53 it failed the connection bro
No, it's just a really short handshake, the line quality is really good so it gets done quick
The subtitles are great
Sounds like military satellite communication
I love the closed captions, cool video!
That's the song I remember of my Pace 56 Voice & Fax (modem) calling Demon Internet (a UK ISP) in the late 90s. 🖥🎤📞🎶
1:42 that's the famous one
Most of us never really heard the 56k one because all the ISP's were using kflex and all of us were using X2...plus even if you weren't it would be a miracle if your line was clean enough for it to connect at full 56k.
the subtitles are a masterpiece
best Wi-Fi in Egypt be like :
OK, now YOU have taken vintage modem-ing to a WHOLE new level here! Forgotten Machines SALUTES what you have done here! I'd love to see MORE videos like this, and even a display like this at a VCF somewhere...would that ever happen? Keep up the great work!
I'd love to go to a VCF, but I haven't been able to make the time yet. Midwest is closest, but it's still a ten-ish hour drive. I will definitely bring the Livermore modem and my dial-up servers if I do though!
One day I'll upgrade my computer to one of these.
the subtitles are 🤩
Still faster than my Bell Fiber Internet.
Love the ole USR Courier modems. Very capable modems. I have still have a few of em in my collection including the special sysop deal where they sent me a HST Dual Standard 14.4k that is software upgradable to V.56K (took few years and several updates to get that point). Ran BBS with em in the 1980s and 1990s.
Now I understand why Tron soundtrack by Daft Punk sounded so familiar.
Cool video! I still want to get a HST Modem on day, they are hard to find lol
Half a meg of flash ROM for a modem in 1998. Seems like quite a lot! Thanks for the upload bud!
Whoever subtitled this.... Top effort. I salute you.
🫡
Any chance we can hear some Courier HST connection sounds? maybe HST 9600, and 16.8 kbps and finally 21.6 kbps if there is any difference?
Done! I wasn't getting 21.6 from my gear for some reason, but 9.6 and 16.8 sounded the same, so I just uploaded 16.8: ruclips.net/video/itkYiepHEJY/видео.htmlsi=B_QOf-DIVgm5XDPE It's pretty short, but is actually more interesting after the speaker turns off, so I created another video that leaves the recording running after connecting here: ruclips.net/video/NwTigdJsMFs/видео.htmlsi=d8D8L10dIwCINQD3
@@retrocet Awesome - thank you! I remember this quite well now running a BBS with USR Dual Standards - HST was very quick at negotiating connections. IIRC the first HST - 9600 baud had a 300 baud back channel, and ~16.8 and higher upgraded to 450 baud, which was just enough to made it usable for those programs that would let you chat while transferring files..
@@retrocet OK I was mistaken. HST topped out at 16.8 kbps. However USR could extend v32terbo to 21.6 kbps when connecting to another USR modem. (Terbo is normally limited to 19.2). ATS13=32 and ATS56=220 to do this.
Wow! Thank you for V.FC! I had a "life event" that pulled me off the BBS scene in August 1994, and V.FC was the last connection I used for running my BBS/calling other BBSes. Like a few others here, last time I heard this was a legit 30 years ago..
That's very cool of you to have all of those modems and how you recorded the sounds from them are well-put together too! Keep up the great work! How are you doing by the way? You're such a talented person! ^_^
I remember when 14.4 was considered blazing fast.
Tip: Enable the captions!
W the gyat damn acoustic coupler
Oh wow, an Armada M300! I had one of those for a few years - seriously nice computer, for its time!
Anyone remember the screaming cat modem?
0:52 the disk swap looked so clean, nice
What does 64, 4 and 1 stand for in 9:34 ? How do you figure them out?
World slowest and worst internet ever
this! this is exactly what I've been looking for! thank you for the thorough demonstration.
Today's generation: "Check out my new smartphone! I can totally connect with others!" 1964 Modem: "AM I A JOKE TO YOU?"
Ah, the sweet song of the freakish ears on a stand.
captions are do funny
Nice Cobalt server there.
This is awesome, it's amazing I remember so many of these
Youngsters. When I started, we were using 110 baud modems.
I don’t remember this at all and spent so many hours tweaking the S registers of my zoom 28.8 v.fast. Then again, I do remember I’d usually get 24,000 connections, occasionally a 26,400 and never 28.8 until v.34 came around.
Interesting! I should see if there is V.FC support on one of my Zoom models - maybe it sounds a little different.
Where could i possibly find the software for the Dialogic Diva card. I cant find it anywhere
Can you backup the terminal files on the disk i could use them
can You explain how echo suppression is disabling?
can You explain V22 also?
Oh, I’d very occasionally get this one when the weather was bad and the line was noisy. It was usually a “standard” 56k tone though.
This is awesome with captions.
This computer boots faster than mine.
How about the standards used for v.34 fax transmission? Theres an error correction scheme that happens after the main v.34 sequence of data
First one: 🐑🐑🐑🐑
When the captions said "beeeeggggassssshh" I felt that
i'm glad i know how to dial with rotary phones, because a lot of kids now don't know how :)
24oo baud was the sound at my house when I was a kid - BBSes - I remember upgrading to a 14.4kbps and was blown away with how fast the terminal window drew!
