Subject: ASYNC.EXE v1.0
Date:    January 7, 1994

Async is a program to open Com port 1 or Com port 2, transmit
a data string; and monitor the modem response.

Usage is ASYNC data_string [/2]  [/Txx]

The data string may not contain spaces. The /2 switch is for usage
with Com port 2. The /T switch increases the time the port is keep
open for the modem reply. Valid values for "xx" are 2 through 20.

If the serial port initializes properly "TRUE" will echo to the screen.
If a modem doesn't exist or isn't working, <<TIME OUT>> will echo to
the screen.

The port stays open for a couple of seconds to monitor the modem response.
If necessary, the time out interval can be increased with the /T switch.
/T2 doubles it, /T3 triples it etc.

A dash(-) may be used instead of a slash(/) for the switches,
Case doesn't matter.

This program was evaluated with an XT clone and a 2400bps internal modem
on com 2. If it serves you well, good. If not, enter "del async.exe" at
the DOS prompt and press the enter key!

PS-  You may use the switch, /S, to reduce the amount of data sent to 
the screen.
