Troubleshooting
If your modem indicates an error, try running the SDL program
at a lower serial port rate. If your computer doesn’t have a
16550 UART, a slower serial port rate can make all the
difference.
You can also try running the program on a different PC. An
idiosyncracy of an off-brand PC or an uncommon version of
DOS my hang up the SDL program.
