Having trouble with pins changing state...

Archiver

I am using a BS2-IC and am trying to get more than one pin to go
high, but the instruction to go high coming from the serial port.
Example: The user clicks a number and that pin goes high. Then the
user clicks another number and that pin needs to go high, but the
first one has to stay high also. The problem I am having is that
when I send the command via the serial port, the first pin will go
high, but when I send the command to send the next pin high, that
pin does indeed go high, but the first pin now goes low.

Any ideas?

Here's the command I use each time.

Serin 16,16780[noparse][[/noparse]WAIT(255),PinNumber,PinState]


Thanks....

Jim,
Is your variable PinState a byte? Are you setting the pins high one bit at
a time or by writing a byte? Have you defined the pins as outputs? Just a
few thoughts.
