I'm trying to learn about serial communication techniques using the sample serial code. I am using a Casio BE-300. After changing from seropen to seropenex, I have been able to establish a connection and have been able to write to my pc (hyperterminal). However, I have not been successful in receiving characters from the pc on the BE. Actually, I am receiving them, because if I terminate the pocketc app and start up a terminal program on the BE, the contents of the buffer pops up (whatever I typed using the serial chat app). So I know that the data is coming to me, but the program is not catching it as an event. I apparently never receive a PM_COMMEVENT event message. Any ideas?

Still looking for feedback on this topic, please.

Did you use the example code for the serial port, or did you write that yourself?

I used the example code. I couldn't get it to work at all until I changed from seropen to seropenex. The only other thing I changed is I added some putsl commands in certain locations to let me know if my code got that far.

What do you get back from commsetmask(ret,EV_RXCHAR)?

Does the program ever get into the PM_COMEVENT case?

I doesn't appear that I ever get into the PM_COMEVENT case. I get into the PM_CHAR case. I'm going off of memory here, but I believe when I had a putsl to show me the return from event(1) that I kept getting a PM_COMMAND return, but I'm not sure why.

You can send me your source code (offline) and see whther I can run it on my PocketPC (HP). May take until after the weekend.
