Need help using DIP and connecting at higher than 14.4K

Need help using DIP and connecting at higher than 14.4K

Post by Ted Milkovic » Tue, 14 Mar 1995 02:23:23



I am using DIP as my dial-up script.  I am having problems connecting at modem speeds higher than 14.4K.

Any ideas?

My configuration is:
80486, 1.5 gig, 32 meg RAM, MultiTech Multimodem 28.8K (I've tried two different 28.8K modems.)

Problem - I am trying to force it to connect at 28.8.  It will dial out, I can hear the handshaking, then it starts
with tones and hangs.

I welcome any ideas.  BTW, thanks in advance for your help.

First - it could be your serial port problem (like UART
can't handle the speed and such)...

And second - you may need a proper init string to be sent
to your modem... Either adjust AT_INIT somewhere in the
source, or just
        send AT.......whatever.......\r

in the script...

I'm not sure which upsets me more: that people are so unwilling to accept
responsibility for their own actions, or that they are so eager to regulate
everyone else's.

Use this instead:
        init AT......whatever.......

in the script.

If you use "send" to set up parameters to the modem, they will cancelled by the
default init string.  The init string is sent before every dial command.

1. Need help w/ DIP and connecting at modem speeds over 14.4K

I am trying to use DIP and a 28.8k modem to complete a SLIP connection
at 28.8k.  I can get a connection at 14.4k (I force the modem to
connect at 14.4k). When I try to connect at 28.8k or let the modem
connect at the highest speed available, it doesn't work.  The modem
just makes a lot of varying tones, but will not connect.  The modems
and lines on each side are ok.  Any ideas?  BTW, I do have a 16550
chip on the serial port.  Would using setserial help?  Your help
is welcome.  Thanks for your help in advance.  Could you reply
