56K HSP PCMCIA Modem (Revision 1 and 2)
(Using PCtel 388P chipset)
**************************************
Device Driver: 7.55 Release s8
Modem Type: ISA PNP Card or PCMCIA Card
CPU Type: Intel Pentium CPU technology 166MHz and up
AMD-K6 /166 MMX Enhanced Processor and up
Cyrix 6x86MX PR200 Processor and up

Host Signal Processing (HSP) modem is a software based modem technology.
It is different from the traditional modem in the way it handles the UART and data pump.
Software driver not only takes care of the system interface to the HSP modem but also the
UART and data pump by utilizing excess CPU power. The HSP modem is software upgradable
for increased performance and new features.
BASIC MINIMUM SYSTEM REQUIREMENT FOR 56KBPS CONNECTIONS

Issuses resolve in this issue
=============================
* Improved a-law connection speed.
* Improved connectivity.
* Improved robustness of retrain and rate negotiation sequence.
* Improved connectivity with various types of lines EIA3, EIA4, EIA5
Special Note
============
* The line speed connection will be V.34 only if the HSP modem tries to connect to a
USR X2 56K modem or x2 ISP modem pool.
MEYE Engineering Utilities
==========================
Modem EYE utilitis, MEYE.EXE, allows real-time display on the modem and shows the phone
line condition activities.
Under V.34 connections, you will see a circle constellation.
In K56Flex connections, you will see three straight horizontal lines.
BitR : Determines the BitRate of the 56K modem
BitRate = 32000 + BitR * 2000 bps
For example : BitR of 4 represent a BitRate of 44Kbps.
Sym : Represents the (Symbol Rate) BAUD rate of the 56K modem.
S/N : Signal to noise ratio
CPU Load = Determines how much CPU loading this HSP modem uses.
uC : UnderRun. Should be Zero.
oC : OverRun. Should be Zero

Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
