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.
