I have done some testing on conserver with ASM. please see below.

hold it, we have 4 ASMs :)

Toronto, the center of the... er, never mind :)

thanks for the warning. we have been looking for replacements. however, there is no sign as of
though, AFAIK the ASM has been in used for really looong time and working fine.

I tried sending the break with (ctrl ecl 0) and it succeeded.

so now the problem is to confirm if there will be serial break problem (if terminal servers
send BREAK at inopportune times) ? that testing process looks dreadful ;/

I don't know if i can count on this... since the ASM has been working fine with Polycentre, is it
likely that there won't be serial break problem with conserver?

other than the serial break question, conserver seems working fine with ASM.
