Dropped character question

Greetings,

I got mgetty setup last night and saw one problem that I need to fix
before I can proceed.  

I checked the archives but the search feature is not working, so I thought
I'd ask.  

The problem is that characters are getting dropped.  
Here is my setup.  I have mgetty running on a RedHat 6.0 intel Linux box
with a USR sportster 28.8 modem and another Linux box with a zoom v.34 modem
dialing out through minicom to test it.  I manage to log in properly and it
appears that I can send characters rapidly to the machine running mgetty,
but receiving the data is the problem.  

I tested this by editing a junk file and pasting from an xterm into this
window.  The echoed text is all garbled, but when I refresh the screen, all
the text got into the file properly.  

This indicates to me that the minicom machine is sending properly and that
the mgetty machine is receiving properly.  

My questions are, is the problem due to flow control, and if so, what am I
doing wrong?  

I set Transmit Data flow control to Hardware flow control (CTS) and recieve
data software flow control to off.

Any suggestions or information would be helpful and appreciated.  Below is
some information from the log file.

Thanks in advance.

Chip
