IBMPC: Buffer Full

[tmk]

Converter buffer is small(2) and can be fulled and overrun.

Buffering in conveter will be improved by making its buffer bigger.
Also proper "inhibit" signal would be needed when the buffer is full.

When buffer in AT keyboard is full it sends 0x00 to indicate the error. Big buffer in converter will mitigate the error on keyboard, but may not have effective improvement in fact.

This is not problem so much for practical use in most cases.
