Specifing Hays Extended Command Set in PPP 2.4.1

Specifing Hays Extended Command Set in PPP 2.4.1

[Frank Krauss]

Hello everyone,

I'm attempting to specify a value in a CHAT Script for an AT command
that has a & in it.

This is because it is a Hays Extended Command Set value.  For example:
"" ATX1&S1E1Q0

Whenever I specify this type of command in a String, I get the 
following message:

Can't get terminal parameters: inappropriate IOCTL for device

If I remove the command with the & in it, the rest of the command runs fine.
I know that the command itself is good since when I run it under MINCOM,
the entire stmt runs fine.

The reason that I have to enter this type of command is because I'm attempting
to get a US Robotics Sportster External 56K Fax Modem to work under Linux
and I need to specify this type of Command in my Chat Script.

My DIP Switch setting are as follows:
   1. Up          5. Up 
   2. Up          6. Up
   3. Up          7. Up
   4. Down      8. Down

My Environment is the following:
   1.  Computer is a Pentium II.
   2.  Distribution is Caldera 2.3
   3.  Kernel is 2.4.22
   4.  PPP is 2.4.1

Would someone be able to tell me what my mistake is or how I can get around
this problem?

Yours truly,

Frank Krauss

"" 'ATX1&S1E1Q0'

Try putting it in quotes. The shell is probably interpreting the &
rather than its being sent to the chat script ( give the chat script the
-v option, make sure that you have 
local2.*;daemon.*		/var/log/ppplog
in /etc/syslog.conf and see what is actually sent to the modem)

Hello Bill,

Thank you very much for your feedback.

That was exactly my problem.  I had to put anything that had special 
characters within Single Quotes.  Then It worked perfect.

Just for your Information, concerning this particular Modem, 
I had to specify the exact same string as my first set of AT commands
as was created by the MINICOM program when it iniatializes the Modem.
When I specified that String as my first one, the Modem is now working
great with PPP/CHAT.

Thank you again for your great information.

Yours truly,

Frank
