- You're probably either doing too much multitasking at the time, or your
- terminal program task priority is too low. The Amiga only has a 1 byte
- buffer for incoming serial port communications. If your priority is too
- low on the terminal program, the CPU won't be able to service it fast
- enough to keep up with the incoming data. Same for the multitasking
- issues - CPU can't keep up with the serial port interrupts.
-
- Fixing it requires you to either increase the priority of your terminal
- program, reduce the number of program you're running concurrently (reduce
- multitasking load), or buy a high speed serial port card for the Amiga
- (don't buy a PeeCee (ICK!) card obviosly).
