Hello,

I'm looking for a way to dump a file into a COM2 port (of an 11 years
old PC with WARP 3 on it).
At first I thought that just including in the "IOPL ..." line
the name of the used program (XCOPY) and issuing a command

xcopy file_name com2

would do what I need but it ended with "0 files copied". Does the
"xcopy" expects some acknowledge from "the other side" (which currently
is absent and when it'll be present, I hope to get by with a single
direction RS-232 link) or there is other reason for a copy net
being performed? Do I need some another app?

From some of your replies, it sounds like you might be trying this from
a DOS prompt. If so, try from an OS/2 command prompt, or try with the
"Direct Access to COM ports" option enabled for DOS.

Thanks for everyone who replyed,

the more I looked at that the more I became convinced that there is
a hardware issue that looks like a problem with IRQ3 and how the
motherboard deals with it: when I experimented with

copy /b file com1 (com2, com3)

only dumping to com2 causes the trap while other was OK and in case of com3
(modem) I could even hear clicks resulting of random characters written
into it.

When I attempted to disable the influence of IRQ3 (by changing IRQ
in config.sys without doing anything with the card), no trap occured, only
the command got stuck until CTRL-C.

An attempt to install SIO2K serial drivers replaced the trap when using com2
with error returned by a crashing program.

I think I'll have to give up on COM2 operating with IRQ (it's still used
in non-standard way by Aladin diving computer interface under pure DOS),
buy a PCI card with 2 serial ports and 1 parallel and hope to have
other serial port working.
