[dstrr]

Hello.
Trouble to communicate with APC SmartUPS via serial port.
UPS connected to the com1 port on windows host.
Communication witch hyperterm works well.
There is a log:

YSM

^ASmart-UPS SC1000
n5S0713T63247
m03/29/07
L240.0
B27.10

apcupsd also can communicate with the UPS and works well.

running apcsmart -a ups gives the following:

com1: device reports different attributes than what were set
unable to detect an APC Smart protocol UPS on port com1
check the cabling, port name or model name and try again

ups.conf:
[ups]
	driver=apcsmart
	port=com1
	cable=940-0095B
	desc="test"

Sysinternals Portmon captures the following activity on com1:

Thus, apcsmart sends the Escape character, which is not recognised by UPS and returns NA.
Is there a solution for this issue?
Thank You and sorry for my English.
