I'm attempting to get PPP working. I have a socketmodem connected to an LPC2468 on uart 1. have the serial driver working.
Do I need to include Std_Modem.c in my project?
Where do I make changes to support my particular modem?
I'm not finding this obvious.

Same problem but dropping a ~ every 2 do not work properly. I push a dummy ~ as the very first char in the RX buffer. It seams that there is an unalignement in the PPP framing scheme. My app works like this:
~~FRAME~~FRAME~~FRAME~~...... the first ~ is dummy
My app do not works like this:
~FRAME~~FRAME~~FRAME~~...... dropping every 2nd ~ the PPP still goes up with lot of retrans but then for example if you ping the board it responds only to even icmp packets (PPP decodes 1 frame every 2).
let me know your opinion.
I've been corresponding with Keil support. They agree there is a problem, but they have not fixed it yet.
Hello,
Did the patch fix this problems for you guys?
I updated my version of RL-ARM and am having PPP issues of a different sort. I seem to be able to successfully exchange PPP packets but cannot establish a connection over a null-modem link to a windows PC. I put a forum post up and emailed Keil, but no one has replied:

Any chance you might have some suggestions for me?
Any help would be greatly appreciated, Eric
They fixed the framing problem. However, it still won't connected to a Cisco NAS (Cisco 7206VXR). It fails during LCP parameter negotiation.
Due to this and other problems with the stack, we have made the decision to cut our losses and go with a stack from another vendor.
Okay, thank you. I really appreciate this.
My real use for the stack is to connect with a cellular modem and I have been seeing some LCP errors.
