Improved Modem Support

The same improvements made on the PortMaster 3 in ComOS 3.8.2 are now part
of ComOS 4.0.3.

* A timing problem with V.32 modems is fixed.
* A rate renegotiation and retrain issue with U.S. Robotics (USR) V.90
modems is fixed.
* A disconnect problem that occurred when V.90 falls back to V.34 is fixed.
* A timing problem with LT WinModems is fixed.
* A USR V.90 "No Connect" problem is fixed.
* A latency problem is fixed, improving ping times and reducing game
latency.
* A V.34 renegotiation issue is fixed (including the upstream part of V.90
and K56flex).
* An A-law rate renegotiation problem is fixed.
* The LAPM retransmitter in V.90 is improved.
