>SERI 600 N 8 1 F <cr> changing all parameters

600 N 8 1 FDX

The processor does not allow the following combinations:

• no parity, 7 data bits, 1 stop bit: if this combination is given the

HMP240 programme will change the number of stop bits to 2

• even or odd parity, 8 data bits, 2 stop bits: if this combination is given

the programme changes the number of stop bits to 1

NOTE

The serial bus settings become effective only after reset.

When the half-duplex mode is set, it will automatically turn the echo off. Even

then the ECHO command can indicate that echo is on.
