I would like to know how must I tune my W95 for a connection PPP to the SCO OpenServer 5.0 System. What identification protocol must I to use for an automatic conection from the W95 ?


I think I have the answer but It would help to now more about what have you tryed to do on the Unix side and also what is the
modem manufacturer/brand as this might change things a little.

Normally it makes no difference the modem speed.

I've tried by adding new entries in the gettydefs file, then enabling the serial line to which is the modem connected.

The new entries are copied from the '6' line at 9600, or the 'l','m','n' speeds.

The modems I use, are ZOOM modems 14400 VFX V32.bis and
V.34 Plus External 33.6 Faxmodem Model 2836 (Plug and Play).

I would like to obtain a generic response, because I can use other modems not ZOOM but US Robotix, MultiTech, or others.

Thank you very much.

Try to set the line to 38400, you can make this changing the B9600 to B38400 in the line of the gettydefs.

Good Luck!
Ok.

Try the following.

1- In the file "/usr/lib/uucp/Devices" put the following lines
   ACU tty2A - 19200 zoom
   Direct tty2a - 19200 direct

2- In the file "/usr/lib/uucp/Dialers" put the following lines
   #  Bullet 14400
   #
   zoom =,-,      "" +++\dATZ\r\c OK\r ATS07=60\r\c OK\r   ATDP\T\r\d\d\d\d\d\d\d\c CONNECT
   &zoom =,-,      "" +++\dATH0\r\c OK\r ATZ\r\c OK\r ATS0=1\r\c OK\r ATS07=45\r\c OK

3- disable tty2a; enable tty2A

4- "cu -l tty2a dir" should put you connected to the modem.

As for the rest you should read the manual in the section UUCP

This assumes you have the modem attached to "com2"
The line in inittab that concerns tty2A should have the speed you need to connect with the modem eg: 19200
Also please use the original gettydefs file

Best regards

Excuse-me for the long period of response. I've been traveling and I've get vacances.

Well, your response have been good, but I've added some modifications:

At the Dialers entries, the following commands:

ATV1E1Q0X0&C1&K3

And all the rest have been good. So, thank-you.
