5250 emulation

I am having problems getting connected to the Internet using
Linux 5.2. I can get my modem to dial, but once it connects it
lasts about 3 seconds and then disconnects. Do I need to use
setserial to set the baud rate for the com port itself? I am new
to Linux so I am not sure...I also want to try the tn5250 emulator
if I can ever get connected to download it...I am sure that will 
be a whole new set of problems...Thanks for any help you can 
give me.

Stan
