Fwd: RS232 Homebrew for interface from RS232 to Ham Radio


I found this message in my mailbox and I think it's a good idea to post it not only in comp.sys.hp48 but also here.

I do not post to this group yet. I saw discussion about HP50 signal from RS232.

I built this interface and it works both ways. Many such as this are available already commercially or to build.

Please post to the HP group this information.

Also, I use eCom Station and before OS/2 since 1992.
