Hand-held serial terminal
 

Greetings. I just picked up an Oyster model 4 handheld serial terminal at a
surplus sale. It is about the size of an old TI calculator and appears to
work. After much trial and error I got the baud rate set on it to communicate
with my packet TNC. Does anyone have any documentation on this thing? I am
specifically looking for the way to enter the setup mode. I dropped the
company a line, but after two weeks still have not gotten a reply. I plan on
using this for amateur radio as well as some work related projects. Thanks in
advance. 73 de Bob W8IJG
