I've been putting together a Hypercard stack to control a serial i/o box and was doing quite well. I'm using the Hypercard Serial Toolkit. Everything was fine until I tried to read in data with values above 127 - it seems the recvBytes command accidentally uses the char datatype or something and effectively only reads 7 bits of an 8 bit number!
Does anyone have any experiece of this? Any suggestions - this was meant to be a hypercard project, yes I can and have used other environments, but I would like to get it working in Hypercard.
