That sounds right when the other end does not have hardware-level XON/XOFF, but it should be much faster with a better UART on the PC, like an OX16C950 <https://pdf1.alldatasheet.com/datasheet-pdf/download/161698/OXFORD/OX16C950.html> or a chip from FTDI or MOXA. As soon as the M100 sends XOFF, the UART chip in the serial port automatically stops the flow of data. No lag, no lost characters. I connect using 19,200 bps in BASIC (*LOAD "COM:98N1ENN"* ) and it works perfectly when I use certain USB serial adapters (and not others). Has anyone with a Model 100 tried using a serial card or USB adapter that supports "automated in-band flow-control"? Do you see the same high-speed connection as I do on my Tandy 200? —b9
