Yes, reset_config trst_and_srst didn't help, so my guess was wrong.

By using jtag_reset (together with the above reset_config), I found
that that the dongle can toggle the TRST, but the SRST is unaffected.

Is there any way I can check the other signals?

Can I assume that since it reports things like:

Info : JTAG tap: stm32f1x.cpu tap/device found: 0x3ba00477 (mfg: 0x23b, part: 0xba00, ver: 0x3)

that the TDI/TDO/TCK/TMS signals are ok?

Done:
