So I figure I can try to access my Hayes modem as a test to send an AT command. To do this I thought I would try the microcom applet that comes with busybox. Since this is a linux command, it wants to open a TTY file of some sort. From what I have read elsewhere, I expected to find an entry under /dev with a name similar ttyUSB0. I don't see anything like this. I tried to open /dev/bus/usb/002/002 but that fails as this is a folder. I looked around in the folder's contents looking for something that may be a tty file but I don't see anything.
So maybe from Android rather than Linux? I searched the Play Store for USB and for Serial and for UART. I found several apps which would appear to implement at least simple serial comm via usb->serial adapters (although none claim to support the keyspan). So far, I haven't found one that would work. I have, however, ordered a cheapo USB->Serial cable that says it has a Prolific chipset (I believe the keyspan has a Ti one) and perhaps - after it gets here from China - I will make additional progress.
