Moni is a serial line monitor ("using a serial port") [L1 ] written by Rolf Schroedter.
LV What does it monitor - the data flowing on the serial line?
It's not a terminal emulator, but it shows the incoming data of a serial port in ASCII or HEX. The input may be logged to a file.
Using moni you may also send ASCII or HEX data over the serial port as well as send chunks of data repeatedly.
Moni can be downloaded from (updated link Apr 22, 2003)
