There are two or there ways ways:

--8<---------------cut here---------------start------------->8---
$ gpg-connect-agent
> /let passwd abc
> /definq PASSPHRASE passwd
> preset_passphrase --inquire  example-cache -1
S INQUIRE_MAXLEN 480
INQUIRE PASSPHRASE
OK
> get_passphrase  example-cache X X X
OK 31323334
> # Second version using a hexified passphrase
> preset_passphrase  example-cache -1 616263
OK
> get_passphrase  example-cache X X X
OK 616263
> 
--8<---------------cut here---------------end--------------->8---

There is also a tool which implements the above:

--8<---------------cut here---------------start------------->8---
$ /usr/local/libexec/gpg-preset-passphrase -c -P ABC example-cache
$ gpg-connect-agent 'get_passphrase example-cache X X X' /bye
OK 414243
--8<---------------cut here---------------end--------------->8---
