Hi, Thanks for the response (it's my turn to be late replying as I've been sent by by employer for 2 weeks to a client site with the Bastard Commute From Hell, but I digress)...

Thanks for pointing this out - my ISP is actually quite accommodating so I can't let myself be rude... >Answer 1: > >Enabling async logging should show that we're sending traffic out and >receiving nothing back. If you can get a description from your ISP >of what their ppp implementation has a problem with, I'd be happy to >help further, but without this, my hands are tied :-( OK, will do. I actually thought that changing my dialup to a number with different (not v.90) modems had fixed the problem, but it has shown disturbing signs of relapse... >Of course if any of the above assertions are wrong, please speak up >and I may be able to help :) > >Answer 2: >Does ``set accmap 000a0000'' help ? If it did, that'd be one for the >books :-) I haven't had a chance to try this yet (but will). However, what does this actually mean? I've found the following snippet on the web, but my knowledge of modems is not exactly exhaustive. : If your link freezes as soon as you've connected and you see : a large number of FCS errors, this may be because your link is : not 8 bit clean. Make sure your modem is not using software : flow control (XON/XOFF). If your datalink must use : software flow control, use the command set accmap 0x000a0000 : to tell ppp to escape the ^Q and ^S characters. Off the top of your head, do you know of any good sources that I can use to better educate myself on what is going on here? Thanks for the help - I have a few things to check out now...
