SERI Serial bus settings
SERI b p d s x
b = bauds (300, 600, 1200, 2400, 4800, 9600)
p = parity (n = none, e = even, o = odd)
d = data bits (7 or 8)
s = stop bits (1 or 2)
x = duplex (H = half, F = full)
Giving the command on its own outputs the current settings:
>SERI
4800 E 7 1 FDX
The settings can be changed one parameter at a time or all parameters at once:
>SERI O H changing parity and duplex
4800 O 7 1 HDX
>SERI 600 N 8 1 F 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
HMP228 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
