# v0.7.1 — `sendlnretry`: stop losing commands to a booting device
|
|
|
|
## 🐛 Bug fixes
|
|
|
|
**Scripts no longer hang forever when a device swallows a command**
|
|
* A device that is still booting can silently **discard console input** the moment its shell takes over the tty. The line you sent is gone — the device never echoes it and never runs it — so the `wait` that follows blocks forever and your test rig sits dead until someone notices.
|
|
* This is a race, not a delay: adding `pause` before `sendln` only lowers the odds of hitting the window, it can never close it. In a 45-cycle overnight power-cycle run, 3 cycles hung this way — and the sends that got swallowed landed at *exactly* the same moment as the ones that worked.
|
|
|
|
## ✨ New features
|
|
|
|
**New TTL command: `sendlnretry`**
|
|
```
|
|
sendlnretry '<text>' '<confirm keyword>' [max attempts]
|
|
```
|
|
* Sends the text, then **waits for proof the device actually ran it** — and **resends** if that proof doesn't arrive. Omit the attempt count and it retries until it gets through.
|
|
* On success `result = 1`. If it runs out of attempts, `result = 0` and **the script keeps going**, so you can handle it yourself:
|
|
|
|
```
|
|
wait 'root@(none):/#'
|
|
sendlnretry 'tpm2' 'TPM 2p0' ; retry until the DUT really runs it
|
|
wait 'PASS'
|
|
|
|
sendlnretry 'tpm2' 'TPM 2p0' 3 ; or cap it and handle failure
|
|
if result = 0 then
|
|
dispstr 'tpm2 got no response after 3 tries'
|
|
endif
|
|
```
|
|
|
|
* Pick a confirm keyword from the command's **output** (`TPM 2p0`), not its echo (`tpm2`) — a tty echo comes from the kernel and doesn't prove the shell ever read the line.
|
|
* Each send clears the receive buffer first, so a match can only come from *this* send; on a hit it consumes only up to the **first** occurrence, leaving the rest for your next `wait`.
|
|
* Per-attempt timeout follows `timeout` / `mtimeout` if you set them, otherwise **3 seconds**. (Unlike `wait`, `0` doesn't mean "wait forever" here — that would mean never retrying.)
