Com port problems?

[chavez@iago.nac.net]

I am having problems configuring a PnP Motorola ISDN BitSURFR Pro EZ terminal adapter under OpenBSD 2.2.  It worked fine under Linux, and would respond to such commands as 'echo ATZ > /dev/cua00' (the modem is on com1.). Under Linux I used minicom to make all my connections. Under OpenBSD 2.2, If I use that same echo command, The modem RD/TD led's will not respond at all. I don't know if it is a matter of the IRQ settings (which I have exhausted the motorola's archives for a spec list). If you have any information/commands for me to try, please send them to condor@iago.nac.net. Thank you very much for your time and consideration.
