- In this directory you find the sources for papi:
-
- PAPI is a Packet driver for the isdn common API.
- It is a MSDOS terminate and stay resident program.
- Compiled with tcc and tasm.
-
- The Common ISDN API (ISDN-CAPI) is an interface defined by german telecom
- and german ISDN Cards manufacturer.
- The ISDN-CAPI supported is version 1.1, Profile A of 7.Sep.90
-
- The packet interface implemented is version 1.09.
- The implemented class is slip.
-
- This version:
- VERSION 0.20 05.Oct.1993
-
-
- The newest version will always be available through ftp.germany.eu.net.
- If you do not have access to ftp use their mail server:
- send mail to <archive-server@Germany.EU.net> and place the keyword "help"
- in the body of the mail.
-
- History - Why I wrote it:
- I use a small 286 MSDOS box as a router to the Internet (EUNET).
- The box is equipped with an ISDN card and an ethernet card.
- It connects my small network to the EUNET-POP via ISDN.
- The packet driver which came with the first ISDN board was not very
- stable.
-
- I found a not too expensive ISDN board from teles Berlin.
- Their software interface is the ISDN-CAPI. The board is very simple
- (only two chips from Siemens). It is not intelligent (i.e. it does
- not have a processor on board).
-
- I use ka9q and pc-route as routers.
- The only part missing was a piece of software interfacing ISDN-CAPI
- and ka9q. ka9q supports the packet driver interface very well.
- papi is the missing link.
-
- Restrictions:
- - only 1 application registered per program.
- - only 1 controller supported per computer.
- - only 1 papi packet driver per computer
- - only 1 ISDN destination and the destination is fixed at the time
- the driver is invoked.
- - a tcp/ip packet has to be <= 2K
- - only X75 and HDLC-UI frames as supported level 2 protocols.
- - only tested with ka9q
-
- It works now with Dr. Neuhaus Niccy 3008 and Niccy 1000 cards.
- With AVM-A1 and Teles S0 Boards.
- I did not arrive to make the packet driver work stable with the Diehl
- implementation of the CAPI. It might be the problem of my packet driver.
- Anyway they sell their own packet driver.
- The packet driver is exercising the interrupt scheme of a CAPI.
- It is working in a heavily interrupt driven environment.
-
-
- How to use PAPI:
-
- First install the CAPI Interface you get with the ISDN-Card.
- Then install papi. It is a Terminate and Stay Resident (TSR) program.
- Then install the application you want to use i.e. ka9q.
-
- Installation of papi:
-
- papi [-v] [-x] [-u] [-o eaz] -n telno [ -N telno1 ]
- [-p PacketIntNo] [-c CAPIIntNo] [-w Timeout] [-s BufSize]
- [ -S BufSize1 ]
-
- -v The packet driver is verbose when installing.
- -V LN The packet driver is writing a status into line LN of the
- display. Status resembles the display of an ISDN-Telephone.
- -x Layer 2 protocol X75
- -u Layer 2 protocol UI-HDLC Frames (default)
- -c INT Soft interrupt of ISDN-CAPI (default 0xF1)
- -p INT Soft interrupt of papi (default 0x60)
- -o eaz The digit which selects calls to your card. (default 2). Has to be
- between 1 and 8.
- -n ISDN# The ISDN number of the host you want to connect to. This is the
- only host which might call back. If you do not give a number papi
- is not installed. If the host is not identifying himself with
- his number when calling the call is not accepted!
- If you want to use Semi Permanent Circuits add an 's' to the number.
- The ISDN number is not checked. It is passed directly to the capi.
- -N ISDN# The ISDN number of the host as it is given from the network.
- Under certain conditions the number coming from the network is
- different from the number you have to dial. The packet driver is
- using this number as a sort of password.
- -i ignore. Do not check the incoming caller id.
- -w n The line is disconnected when idle for n seconds. (default 10)
- -s bytes maximal size for ip packets ( default and maximum 2048).
- The actual maximum for NICCY 3008 is 1024.
- -S bytes size used for b2 protocol size.
- -P The driver is working in a sort of polling mode. I.e. instead of
- handling the incoming message in the interrupt only a mark is set
- and the message is handled later in a timer interrupt.
- The AVM-A1 Board is only working with this option.
-
- Examples:
-
- # start the capi for your card:
- START_S0
- # start the packet driver:
- c:\capi\papi -v -n 12345678 -o 3 -w 240 -u -c 0xF1 -p 0x60 -s 2048
- # start your application (i.e. ka9q):
- c:\nett\net -d c:\nett c:\nett\autoexec.net
-
- More reasonable is:
- c:\capi\papi -n 123456 -w 240

- slfp.c, a C-language driver for 8250 slip written by
- Glenn H McGregor, and William A Simpson, served as a
- skeleton for papi.c. The printf is adapted from the 386BSD
- stand alone printf.
- The slightly changed getopt.c is coming with Turbo-C.
- Many thanks to teles GmbH, Berlin and Dr. Neuhaus, Hamburg for their support.
