- Information:
-
- The purpose of this FSC is to focus discussion on particular
- problems in Fidonet(r) and possible methods of solution. No
- proposed solutions in this document are intended as
- standards for Fidonet. Rather, it is hoped that a general
- consensus will emerge as to the appropriate solution to such
- problems, leading eventually to the adoption of standards.
- Distribution is subject to the limitations listed below.

- Modem Handling
- --------------
-
- The current nodelist doesn't provide enought information for really fancy
- handling of modems and connections. With the advent of line sharing between
- modems/faxes certain additions to the nodelist flags are required.
-
- I am currently writing a product which will handle and use the following codes
-
- Y.... where .... can consist of the hardware protocols the modem understands
- A 300 V.21 > Usually one of these flags would be present to
- B 300 Bell 103 > designate the chosen 300 baud hardware protocol
- C 1200 V.22 or Bell 212A
- D 2400 V.22bis
- E 9600 V.29
- F 9600 V.32
- G 9600 V.32 non-trellis coded
- H 14400 V.32bis

- Z.... where .... can consist of the software protocols the modem understands
- A MNP1 Block mode (half duplex)
- B MNP2 Stream mode (full duplex)
- C MNP3 Stream mode with Start/Stop bit striping
- D MNP4 Stream mode with Start/Stop bit striping and large packet sizes

- W No Guard tone
- X 550Hz Guard tone (some European countries)
- Y 1800Hz Guard tone (UK, some Commonwealth countries)
- Z Do reverse carrier processing when dialing this node
-
-
- I am in the process of designing a very sophisticated modem dialing language
- and would like to propose the following additions to the node list
- to help facilitate better modem/line handling with the advent of
- different modem standards etc.
