Dropping the DTR is a much more effective way of doing things.... As Bryce suggested, a "better" way is to close the device, wait 1 sec and then reopen it (with the SAME parameters). I tried it and it works just fine. DTR is dropped properly. Multi-serial manufacturers should ensure that this technique works on their hardware too. -- Marco Papa 'Doc' -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= uucp:...!pollux!papa BIX:papa ARPAnet:pollux!papa@oberon.usc.edu "There's Alpha, Beta, Gamma and Diga!" -- Leo Schwab [quoting Rick Unland] -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
