Which [tcpsend] are you talking about? There are two flavors around:
 * mrpeach (unmaintained)
 * iemnet (recommended)

I checked iemnet's [tcpsend] and it has only one outlet whose sole
purpose is to indicate whether it is connected or not.

It appears that the outlet only sends 0, if the disconnect was
initiated by [tcpsend] itself. It happily stays at 1, if the other end
quits the connection. This is clearly a bug and should be reported:

https://git.iem.at/pd/iemnet/-/issues

Until this gets fixed, you could:

  * replace [tcpsend] with [tcpclient]. Its third outlet reports the
    connection state correctly.

  * use [netsend -b] from Pd which reports connection state correctly
    on the first outlet

Actually, I don't quite see the purpose of [tcpsend] as [tcpclient]
covers all its capabilities. Probably it is there only for historic
reasons.
