I think that I already said that modems exist at near and far ends!

Speeds weren't symmetric back then!

** Just changed the connection speed to 14,400 so now running on rocket fuel on an old data connection laugh***

*** And now running at 28,880! Seems that is the limit for data calls unless one has ISDN provisioned (?)


HSCSD managed 14,400 with a following wind if you had the "latest tech" (ie, 1997 !) type kit. Hardly any networks then supported it - I remember Orange did.

56k half-duplex? Sounds about right.


PC industry modems were all full duplex, upto 33.6kbps, but with 56k (V.90 / V.92) the speeds were limited on the return path. This worked as the ISP ran modem banks generally fed with ISDN trunks (ISDN30) and the home user just had PSTN.

Some non PC systems used half duplex but then ran over "PC industry style" Hayes modems, so the actual PSTN part of the connection was full duplex.
