Serial Input question

Archiver

Serial In question.

I am having problems decoding serial in data from a Midon Designs
Temp 05 module. (All rates are set up to 9600,8,n,no)

I can send info from a hyper terminal pc to the stamp serial port and
data is properly decoded.

Midon temp 05 module sends serial stream properly to pc hyper
terminal.

The problem is when the temp 05 module is connected to the stamp i/p
all data is 255's.

The Stamp i/p is using an Al Williams RS1 inverter/level shifter.

Anybody had a similar problem??

Code is below


{$STAMP BS2p}
'{$PBASIC 2.0}
'{$PORT COM1}

' testing the ser out and in baud mode # 240 for rs 232 line driver
' 9600 8 no parity
