----------------
SET FLOW RTS/CTS is rational only for the hardware serial ports,
COM1..4. If Windows messes up and Kermit can't verify the IRQ then Kermit
uses the Bios pathway, and that's not hardware.
I wish there were one piece of advice we could offer on using any
serial comms program in Windows, but (aside from "please don't") there
isn't. Windows provides ample facilities to fail, both by overdriving
the lesser UART chips (8250 class) and by inadequate Windows serial drivers
as well as not giving enough service time to the real serial hardware.
I guess as close as we will come is if the port fails then slow down.
