I've never had any problems at 19.2K using Windows so, as John suggests. there may be Linux-specific issues.
There are buffers in most if not all USB-RS232 adapters and also in the program on the PC at the other end, and sometimes these need to be tuned a bit. When I send a 25K file from TeraTerm to an M100, TeraTerm finishes in 1/2 minute or so, but the M100 still receives data for another minute. And don't forget that TEXT is usually effectively faster for transferring files since it doesn't have to display or scroll. m On Tue, Dec 12, 2023 at 5:43 PM Brian Brindle <bbrin...@gmail.com> wrote: > > This has come up in discussion a few times so I wanted to show that 19.2Kbps > on the Tandy 100 is possible with only software flow control. > > Here is a video of me creating a 500 line 40 col file that is 20KB, > transferring it to the M102 and back again using the 19.2Kbps serial > connection.
