I'm having a difficulty with an Intel 8052AH-BASIC microcontroller chip on Micromint's BCC52 processor board. I would appreciate some help. I'm having a problem programming an interrupt service routine to handle character input from the console port, which is normally used by basic. Nothing in the manual suggests I can't do this, in fact they try to give all the information that is necessary. I've tried several things but I can't get it to work. The ISR simply echos the character back by retransmitting it. I'm using my PC and procomm to feed it characters. My problem is that I don't know if: there is some reason I can't use my PC to test it like this. there is some other trick, not mentioned in the documentation. this is not possible, because of basic. the documentation is wrong. etc It could be any number of things. If there is someone who can advise me please contact me ASAP. I'm looking for someone who is familiar with this area of the 8052AH-BASIC, and/or might have a code fragment that will help me.
