Both the Hayes 9600 V-series and the $74 2400 card-modem I have won't accept an ATS11 value (DTMF duration) of less than 50ms. The default seems to be 100ms. The Hayes will take a smaller value, but use 50 during tone generation. The clone returns ERROR for a value less than 50. The old 1200 geniune Hayes that I have will take values down to 1ms, and actually do it as well. Since my switch will reliably take 36ms, I see no reason to not allow me to dial at that speed. Anybody (Toby?) know why the newer modems are handicapped/differently-abled in this manner? Steve Forrette, forrette@cory.berkeley.edu [Moderator's Note: And while Toby is answering that, here is another question: how come US Robotics has a condition you can set which allows for 'quick dialing', or dialing without waiting the obligitory two seconds before starting? Hayes used to claim (maybe still do) that telco tariffs require a two second pause before dialing. You could not set that particular S-register less than 2. Telebit seems to feel the same way ... but USR lets you go off hook and bang those digits right out if you set the register for it. PAT]
