Still playing around with the BCR TTL serial port. ...yes it has it's limitations... half duplex, no flow control, bit-banged
..but it is fast! Today I was able to get 32kB transferred in 7 seconds. That's pretty close to 100% utilization on the 57600 baud line. I think that is a new M100 record. It might need independent verification! (why? to reduce time for CP/M disk backups. 4MB will take a 1/2 hour with this approach, or more than an hour at 19200 baud.) Steve
