I have an internal modem(not sure what brand) that works fine, but i want to switch to an external incase the modem needs a hard reset we dont have to shut the machine down.
Its been sooo many years since i used an external modem so im kinda rusty. sofar, i got it to communicate with the sportster (both minicom and mgetty) i can get minicom to establish a terminal connection and transfer a file(by connecting with another computer and hitting 'ATA' when i saw the 'RING') the file transferred fine so i assume the modem is good. but when mgetty tries to answer i get this: 01/03 10:50:45 yS0 waiting for line to clear (VTIME), read: [0d][0a] 01/03 10:50:46 yS0 removing lock file 01/03 10:50:46 yS0 waiting... 01/03 10:50:46 yS0 select returned 1 01/03 10:50:46 yS0 checking lockfiles, locking the line 01/03 10:50:46 yS0 makelock(ttyS0) called 01/03 10:50:46 yS0 do_makelock: lock='/var/lock/LCK..ttyS0' 01/03 10:50:46 yS0 lock made 01/03 10:50:46 yS0 wfr: waiting for ``RING'' 01/03 10:50:46 yS0 got: x[fe][00][80]x[00][ff][80][80][f8]x[e0][80][80][80][f8][00]x[fe][00][80]x[00][ff]x[fe][00][80]x[00][ff][80][80][f8]x[e0][80][80][80][f8][00]x[fe][00][80]x[00][ff] 01/03 10:50:56 yS0 mdm_read_byte: read returned -1: Interrupted system call 01/03 10:50:56 yS0 wfr: timeout waiting for RING 01/03 10:50:56 yS0 wfr: rc=-1, drn=0 01/03 10:50:56 yS0 huh?
