There could be number of things going on. One thing to start with is to get
setserial on your TS7800. Simply download it from here:
http://sourceforge.net/projects/setserial/
load it onto your TS7800 and then issue
./configure
make && make install
It will likely complain about not having a man directory but that only affects the
installation of the man page. Everything else works fine. However, I suspect
that this may not fix your problem. If you post your serial code we can look at
it and may see something affecting your setup. Serial ports can be tricky to
get right.

I have similar problems when I try to use ttts4, the COM 3 header on
TS-7800. My original serial code works fine on my Linux laptop, but
when I ported the code over, I got garbage. I suspect the TS7800
com3 baudrate wasn't set according to what I stated in my serial
code. But I try to use "setserial" command in TS7800, but this
command wasn't installed. I wonder in shell or in the script, how
can I set the baudrate to be permanent to the number I want for
various serial ports?
