Try lowering the port speed
Older PCs may have weak UARTs that are not capable of high speed communications. As a result, you may get frequent dropped connections and/or poor modem performance due to resent packets.
To test this, try lowering your port speed to 38400 or even 19200. If the dropped connections cease, a slow UART may be the problem. A replacement serial port card should fix the problem.
For use with a 56K modem, you want at least 16550 UART. Internal 56K modems should include a 16550 or higher UART on the card.
