SERI Serial bus settings

SERI b p d s x <cr>

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 <cr>

4800 E 7 1 FDX

The settings can be changed one parameter at a time or all parameters at once:

>SERI O H <cr> changing parity and duplex

4800 O 7 1 HDX

>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

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
