ABSTRACT:

Comx218.exe contains the latest version of aiocomx.nlm (version 2.18, dated
November 3, 2000). 
This version of aiocomx.nlm addresses previous limitations where connections
were unreliable at speeds over 19200 through 16550 UARTS.  Comx218.exe also
contains fixes for WAN link issues involving disconnects, incompletely
downloaded web pages and files, and slow IP traffic.

ISSUE: 

Issues resolved in comx218.exe:
1)The read/write buffer size has been increased from 1k to 8k.
Prior to this change, users were unable to browse the WEB reliably via NIAS.
WEB pages failed to completely load and would eventually timeout. Asynchronous
downloads averaged around 1.1K/sec, making this unusable in a production
environment. 
In comparison, a DIGI Card or Stallion Card, with the speed set to 115K could
download and browse at approximately 5.2 - 5.5 K per second. (WEB Browsing and
downloads through NIAS were previously only reliable on a multiport board.) 
With this version of AIOCOMX.NLM, the browsing and download speeds now compare
to those of a multiport card.

Known Issue:
With this r/w buffer size change, you may notice RECEIVE OVERRUNS and RECEIVE
CRC errors as seen in MONITOR | LAN/WAN Drivers | <enter on the selected
interface and Tab to display the details.>  However, these errors are cosmetic,
invisible to the end-user and do not appear to affect performance or data
integrity.

Issues resolved in comx216.exe:
1) Volumes dismounted after NIAS Remote Access attempted to determine which
ports had modems attached.
2) Asynch WAN connections experienced broken links.
3) Slow IP traffic over Asynch WAN connections.
