- Amiga Compunet Modem Drivers
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- The following modem drivers can be found on this disk in directory
- :devs/cnet_modems:
-
- amstrad_sm2400 (by J Davison JD16)
- astracom_1000 (by Dave & Mike ARIADNE)
- direct (by Dave & Mike ARIADNE)
- dumb_1275 (by Eddy Carroll ALLANON)
- microcom_ax (by Dave & Mike ARIADNE)
- microlink (by John Chasey ZUGGER)
- miracle_ws4000 (by Dave & Mike ARIADNE)
- pace_linnet (by Dave & Mike ARIADNE)
- pace_linnet1200 (by John Chasey ZUGGER)
-
- Thanks to everyone who developed drivers - especially ALLANON, since the
- dumb_1275 driver was quite an achievement!
-
- If you have a modem not on this list, one of the existing drivers may well
- work fine. If not, you'll have to do some delving in your modem's
- documentation to create a suitable driver - assuming you succeed, please
- let us know!
-
- New-style modem drivers are ASCII text files and can be edited with a
- simple text-editor like ED or MEMACS. An possible example is as follows:
-
- 1200,1200:1200:Z,E0,\N0X3&D2S2=0S10=20
- 75,1200:1200:Z,E0,X3&D2\N0%F1\J1\W0S2=0S10=20
-
- The first two numbers are the send and receive baud-rates. The third
- number is the "real" baud-rate, with which to talk down the Amiga serial
- port. The rest of the line is a list of Hayes commands to setup the
- modem, separated with commas - this example is for a Microcom AX modem.
-
- Note that the driver can contain several lines if the modem supports more
- than one baud-rate. Note that the driver should contain AT LEAST an E0 to
- switch off modem command echo - drivers with no Hayes commands are taken
- as being for direct connect to the system.
-
- Notes on individual drivers follow:
-
- amstrad_sm2400
- ~~~~~~~~~~~~~~
- Used with an Amstrad SM2400 modem, at 75/1200 or 1200/1200.
-
- astracom_1000
- ~~~~~~~~~~~~~
- Used with an Astracom 1000 modem, at 75/1200. Note that this modem
- doesn't seem to detect DTR dropping correctly, so you'll have to
- manually disconnect it (press RESET) when you leave.
-
- direct
- ~~~~~~
- We wrote this one for direct connection to the system at Cnet towers
- in Perival - then Fintan figured out how to use it to connect via PSS.
- Contact Fintan (FF2) if you want to know how he did it.
-
- dumb_1275
- ~~~~~~~~~
- This was ALLANON's mega-hack - the Amiga isn't supposed to be able to
- support split baud-rates! Eddy's notes - as uploaded to the system -
- are as follows:
-
- This is a modem driver that I've written for the Compunet Amiga terminal
- software which will let you logon with a non-intelligent 1200/75 modem (ie
- one which doesn't support speed buffering). I have only tested it with the
- OEL Telemod2, but it should work with other cheap, dumb modems as well.
-
- First of all, you need to make sure your serial cable is connected up
- properly. The cable I use is connected as follows:
-
- Amiga Serial Port Modem
- ----------------- -----
- Pin 2 <----> SEND PIN
- Pin 3 <----> RECEIVE PIN
- Pin 7 <----> SYSTEM GROUND
- Pin 8 <----> CARRIER DETECT
-
- You should use the SETUP menu in the Compunet software to set the modem
- name to DUMB_1275 and to make sure that the send rate and receive rate are
- BOTH set to 1200. Save these settings to save you having to set them in
- future.
-
- To actually logon, dial the number of the nearest ISTEL node and when you
- hear the carrier, press the modem DATA or CARRIER button (or do whatever
- you normally do to connect your modem). Once you hear ISTEL sending out
- the logon screen (it sounds like a lot of high-pitched noise), select
- CONNECT from the Compunet menu. The timing is quite important here - too
- quick and Istel won't respond correctly to the logon commands sent by the
- Amiga; too slow and Istel will timeout. I've found that selecting CONNECT
- about 4-5 seconds after the Istel carrier has been detected gives
- consistently good results.
-
- After this, it's all automatic, and you logon to Compunet as you would with
- any other modem.
-
- microcom_ax
- ~~~~~~~~~~~
- This is for the Microcom AX series of modems at 75/1200 or 1200/1200,
- such as the Tricom 48/24 MNP.
-
- microlink
- ~~~~~~~~~
- This is for the Microlink modem, at 75/1200 or 1200/1200. To connect at
- 75/1200, you need to put a /75 after the phone number.
-
- miracle_ws4000
- ~~~~~~~~~~~~~~
- This is for the Miracle WS4000, at 75/1200.
-
- pace_linnet
- ~~~~~~~~~~~
- This is for the old Pace Linnet, at 75/1200 only.
-
- pace_linnet1200
- ~~~~~~~~~~~~~~~
- This is for the newer Pace Linnet 1200, at 75/1200 or 1200/1200. To connect
- at 75/1200, you need to put a /75 after the phone number.
