[cctalk] Hayes numeric codes

[RETRO Innovations via cctalk]

I received a bug report today concerning tcpser (the 
Linux/Unix/Windows/MacOS modem emulator) and numeric response codes.


https://github.com/go4retro/tcpser/issues/31

I knew long ago that not all codes and commands were common/consistent 
among modem manufacturers, but I guess I didn't realize even response 
codes differed quite a bit.  After receiving the bug report, I did a bit 
of research, and found, for instance, CONNECT 19200 differs:


Hayes - 14: http://www.bitsavers.org/.../Hayes_44-012_Technical... 

Conexant - 16: 
https://web.archive.org/.../documenta.../dial_up/100498D.pdf 

USRobotics - 85: 
https://support.usr.com/.../5610a/5610a-files/5610a-user.pdf 

Phoenix Contact (industrial modem) - 16: 
https://files.realpars.com/.../um_en_psi_data_basic_modem... 

Supra - 16: https://www.manualslib.com/.../Diamond-Supraexpress-56e.html 

Multi_Tech -19: 
https://www.multitech.com/.../public.../manuals/s000316a.pdf 



I have two questions for the group, if folks can assist:

* Since I purport to be Hayes compatible, I should use the Hayes code 
when available, but the reference above does not go above 38400 bps.  
Did Hayes make a modem that went faster (DTE speed?) and if so, can I 
get a scan of the manual to ensure the codes I am using are the best ones?
* Any other modem manufacturers anyone is aware of, with manuals I can 
check.

[cctalk] Why the Floppy Disk Just Won't Die

https://www.wired.com/story/why-the-floppy-disk-just-wont-die/

Take what you want from the article, but I thought the end paragraph, 
noting that Tom Persky of floppydisk.com is 73 and is only planning to 
handle things for 5 more years.  After that, he thinks the company will 
not transfer to anyone.


Interesting thoughts there.
