How to use 'stunnel' in client mode to accept connections on pty from local programs like 'ppp' instead of 'accept=IP:PORT'?

'pty = yes' seems work in server mode only, so when I removed
'accept =' from 'stunnel' client config I'm getting the error:

[!] Service [ppp]: Each service must define two endpoints on stunnel-5.44

I need to call 'stunnel' client from 'pppd' and communicate with 'stunnel' using pty if it was possible by using a command:

pppd /dev/ptyp3 local debug noauth passive noccp novj novjccomp nopcomp noaccomp name ppp-client connect 'stunnel /etc/stunnel/stunnel-client.conf'

Both 'pppd' and 'stunnel' started by executing the command above, but 'pppd' can't communicate to 'stunnel' server using pty.

Please advice.

client = yes
accept = [ ](
connect = STUNNEL-SERVER-IP:723
CAfile = /etc/stunnel/ca.crt
cert = /etc/stunnel/client.crt
key = /etc/stunnel/client.key
verifyChain = yes
checkHost = hostna.me
;checkIP =
