on pc2 there's Sysinternal Portmon capturing events on com8 and com9
com1 on pc1 is a real com port
com8 and com9 are two pl2303 serial emulators
hub4com is on pc2, started with
hub4com --route=all:all --baud=9600 --octs=off \\.\COM8 --baud=9600 --octs=off \\.\COM9
when i write "AT" command on hyperterminal to com1 on pc1, hub4com on pc2 routes it from com9 to com8, the modem answer with "OK", hub4com routes it from com8 to com9, but i see nothing in hyperterminal on pc1.
The same if i send other commands.
Only after i closed hub4com with ctrl-c, the "OK" and all other modem responses appears on hyperterminal on pc1!
How can i read message on my hyperterminal on pc1 when i just sended commands?
on follow the portmon log (serial2 is com8, serial3 is com9)
Hi, Thanx for the program!
This is my situation

I see that hub4com successfully writes "OK" to
Serial3/com9 so it looks like a problem with pl2303.
Did you tried to test it with:
hyperterminal---pc1(com1)---(nullmodemcable)---pc2(com9)---hyperterminal
Yes, I tried and it worked correctly!
