I see nobody has tried to help you yet.  So I'll try - at what might be a 
very simplistic level.

Some time ago I worked with UNIX on Sun SPARC workstations - specifically 
trying to get a dongle to work on a serial line.  I seem to remember that 
the system calls used to access the serial line were critical.  There 
were several options to define how and when the serial driver reported 
the arrival of a character to the calling program - one was immediate and 
occurred with every character (as you would like) but most of the others 
assumed you wanted a line of data before the call returned - so either 80 
characters or a timeout of about a second was a typical default.  

Now of course you're not writing code.  I think the same control settings 
were available in some sort of driver configuration setup - some option 
in "stty ....".  At risk of being dammned, have you tried the man pages?

Hope this helps .....

Just a little note, which may or may not help:
I use a Creatix VFi 14.4, an internal modem, also IRQ5, with Rockwell
chipset, together mith the excellent mgetty/sendfax package and Linux
2.0.29. Instead of using cua2 I use ttyS2, as the docs in mgetty told me
so (I think its a difference in how the lock-files are made), and I have
not recognized the above problems. So maybe ttyS2 may help?

hope this helps,

Thanks to all the people who sent mail saying read the man pages!!!
What a complete waste of bandwidth. If you read the above, its clear I
know how to use stty and setserial to config a serial port.

Anyway, no-one's came up with any answers, but I'd like to add this:
I did a RedHat 4.1 install on a spare disk which I stuck in my machine
just for the install. Curiously, using exactly the same setserial and
stty commands - the modem works fine - discuss????

Paul.
