So let me make sure that I understand correctly... This does NOT happen when using faxsend? The tcsetattr problem only occurs with pagesend?
The OK response after ATH0 is encouraging... it doesn't look like before.


Lee.
I've been wondering if its the way we have the modems set up?
We have out modems connected to a stallion port server and a small program running on the linux servers that maps a pseudo device pttya4 to ttya4 device?
The srv_tty progarm connects to an ip number and port on stallion port server.
This is a link to the app used (if it makes the clearer on the how I have things set up):
http://www.stallion.com.au/html/download/es2-utilities.html
http://stallion.com.au/html/userdoc/esii/es2_unix/es2_use_unix4.html
Could it be that pagesend dose not communicate with the pseudo devices?
FaxSend seems to work ok with this sort of set up?


I was just looking at the README for this svr_tty app.. Which may explain why the Parity didn't change to odd or none, however, I don't think it explains why sendfax works and pagesend did not? (for me at least)

The use of a UNIX pseudo-tty imposes some limitations, although
these are not normally a problem for most applications.  The same
limitations occur in other situations where pseudo-ttys are used,
e.g. a remote login connection using telnet or rlogin.

The major difference between a real serial port and the pseudo-tty
which provides a reverse telnet connection is that hardware-related
characteristics such as baud rate, number of bits per character,
hardware flow control, etc. cannot be set by the application program
using the normal UNIX tty device API (ioctl).  These characteristics
must be configured in the Server using the facilities it provides
(web interface, command line interface, configuration files, etc.)
