On the wallstreet, at least, (and possibly on the Lombard, if Paul could check that the FCR bits are actually the same), without this delay, the modem will not answer to AT commands. This causes almost all PPP dialers out there to fail with their default scripts. It's possible to work around this on some dialers (kppp has a tempo setting) but not all of them. That's the main reason why we added this code. (I think Paul added the clean sleep code, I originally throwed an horrible mdelay() which locked the entire kernel waiting for the modem). -- Perso. e-mail: Work e-mail: BenH.
