Dip Switch Settings; Xon/Xoff Protocoll; Command List - Hameg Instruments Hm8131-2 Handbuch

commands that have been passed to the interface in the
string. Afterwards the baud rate is also redetermined.
Automatic baud rate detection
The first character that must be sent to the interface
when power on or after the #BD command is a space
(20h). The interface needs it to calculate the baud rate
used for transmission, and automatically adapts it to it. If
any other character or an incomplete character is
received, the system is prevented from working.

Xon/Xoff protocoll

The command #x1 is used to activate so-called software
handshaking (it is encountered by the command Xo). In
software handshaking mode, data transfer between the
computer and the interface is no longer synchronized by
the hardware lines; instead, this function is performed
by 2 commands:
Xon = 11h = continue transm.
Xoff = 13h = halt transmission
Subject to change without notice

Stop bit(s)
Parity

End of transmiss.
