Serial cable pinout for Winradio WR-1550?
 

Hi!

Just bought an old external WR-1550e receiver, but there was no serial cable
with it. I thought usual modem or null-modem cable would do fine, but the
gear seems to be not willing to co-operate... Anyone having an idea how the
cable should be wired? I tried to google with no luck.
