2 | ; PPP.ASM |
||
3 | ; |
||
4 | ; Compile with FASM for Menuet |
||
5 | ; This program dials into an ISP and establishes a PPP connection |
||
6 | ; |
||
7 | ; Version 11 26th January 2004 |
||
8 | ; |
||
9 | ; This code is a port of the PPP dialer program by Microchip, from |
||
10 | ; their application note AN724 |
||
11 | ; It has been ported by Mike Hibbett mikeh@oceanfree.net for Menuet |
||
12 | ; |
||
13 | ; 26/1/04 - Mike Hibbett - added support for com port selected by |
||
14 | ; stackcfg |
||
15 | ; 2/5/03 - Shrirang - Added Abort Strings To sendwait to get out early |
||
16 | ; if modem sends abort strings like NO CARRIER etc. |
